ChangeSet@1.1165.1.1, 2003-04-21 13:24:30-07:00, rml@tech9.net [PATCH] trivial task_prio() fix Here is a trivial fix for task_prio() in the case MAX_RT_PRIO != MAX_USER_RT_PRIO. In this case, all priorities are skewed by (MAX_RT_PRIO - MAX_USER_RT_PRIO). The fix is to subtract the full MAX_RT_PRIO value from p->prio, not just MAX_USER_RT_PRIO. This makes sense, as the full priority range is unrelated to the maximum user value. Only the real maximum RT value matters. This has been in Andrew's tree for awhile, with no issue. Also, Ingo acked it. ChangeSet@1.1166, 2003-04-21 13:10:51-07:00, torvalds@penguin.transmeta.com Allow gcc to generate better code for irq handling. Ok, now that most drivers have been converted to the new irqreturn_t, we can remove the fascist type-checks and just use a regular integer type which has a simpler calling convention.

Hence, this "FIXME: do not do for zone highmem". Presumably this is a question of policy, as highmem allocations may be satisfied by reaping slab pages and handing them back; but the FIXME says what we should do.

There are 3 things I didn't like in the patch. 1) The patch allocates 15 pointers instead of 15 hd_structs. (incase of s= csi). I was really hoping to get rid of "15" and make it really dynamic. (In ca= se if we ever want to support more than 15 partitions per disk etc..).=20 I was thought about making it a linked list, but blk_partition_remap() needs to get to hd_struct for a given partition everytime we do IO. So linked list would be bad, we really need direct access to partition in= fo. 2) I had to add "partno" to hd_struct, since part_dev_read() used to calc= ulate partition number from the address before. 3) kmalloc() failure in add_partition() will be silently ignored. It saves 2048 bytes per disk.

It is better that swapoff be the first choice for OOMkill. The patch changes the oom-killer so that it will kill off any currently-running swapoff instance before killing any other task.

ChangeSet@1.1124.3.26, 2003-04-20 14:28:39-07:00, akpm@digeo.com [PATCH] Disallow swapoff if there is insufficient memory From: Hugh Dickins First of three small "stop swapoff" patches based on 2.5.67-mm3: stop swapoff 1/3 vm_enough_memory? Before embarking upon swapoff, check vm_enough_memory. Mainly for consistency in the overcommit_memory 2 (strict accounting) case: fail with -ENOMEM if it wouldn't let the amount removed be committed. Will always succeed in the overcommit_memory 1 case, as it should in root-shoot-foot mode. In the overcommit_memory 0 case, well, I don't care much either way, so opted for the simplest code: no special case. Which means it could now fail at the start; but that's unlikely (case 0 is over-generous) and only when it would have got stuck later on anyway.

ChangeSet@1.1124.3.22, 2003-04-20 14:28:12-07:00, akpm@digeo.com [PATCH] implement __GFP_REPEAT, __GFP_NOFAIL, __GFP_NORETRY This is a cleanup patch. There are quite a lot of places in the kernel which will infinitely retry a memory allocation. Generally, they get it wrong. Some do yield(), the semantics of which have changed over time. Some do schedule(), which can lock up if the caller is SCHED_FIFO/RR. Some do schedule_timeout(), etc. And often it is unnecessary, because the page allocator will do the retry internally anyway. But we cannot rely on that - this behaviour may change (-aa and -rmap kernels do not do this, for instance). So it is good to formalise and to centralise this operation. If an allocation specifies __GFP_REPEAT then the page allocator must infinitely retry the allocation. The semantics of __GFP_REPEAT are "try harder". The allocation _may_ fail (the 2.4 -aa and -rmap VM's do not retry infinitely by default). The semantics of __GFP_NOFAIL are "cannot fail". It is a no-op in this VM, but needs to be honoured (or fix up the callers) if the VM ischanged to not retry infinitely by default. The semantics of __GFP_NOREPEAT are "try once, don't loop". This isn't used at present (although perhaps it should be, in swapoff). It is mainly for completeness. ChangeSet@1.1124.3.21, 2003-04-20 14:28:04-07:00, akpm@digeo.com [PATCH] shmdt() speedup From: William Lee Irwin III Micro-optimize sys_shmdt(). There are methods of exploiting knowledge of the vma's being searched to restrict the search space. These are: (1) shm mappings always start their lives at file offset 0, so only vma's above shmaddr need be considered. find_vma() can be used to seek to the proper position in mm->mmap in O(lg(n)) time. (2) The search is for a vma which could be a fragment of a broken-up shm mapping, which would have been created starting at shmaddr with vm_pgoff 0 and then continued no further into userspace than shmaddr + size. So after having found an initial vma, find the size of the shm segment it maps to calculate an upper bound to the virtualspace that needs to be searched. (3) mremap() would have caused the original checks to miss vma's mapping the shm segment if shmaddr were the original address at which the shm segments were attached. This does no better and no worse than the original code in that situation. (4) If the chain of references in vma->vm_file->f_dentry->d_inode->i_size is not guaranteed by refcounting and/or the shm code then this is oopsable; AFAICT an inode is always allocated.

Since we're doing lost-tick compensation outside timer->mark_offset, time can pass between time-source reads which can cause gettimeofday inconsistencies. Additionally detect_lost_tick() was broken for the PIT case, since the whole point of detect_lost_tick() is to interpolate between two time sources to find inconsistencies. Additionally this could cause xtime_lock seq_lock reader starvation which has been causing machine hangs for SMP boxes that use the PIT as a time source. This patch fixes the described race by removing detect_lost_tick() and instead implementing the lost tick detection code inside mark_offset(). Some of the divs and mods being added here might concern folks, but by not calling timer->get_offset() in detect_lost_tick() we eliminate much of the same math. I did some simple cycle counting and the new code comes out on average equivalent or faster.

ChangeSet@1.1124.3.7, 2003-04-20 14:26:28-07:00, akpm@digeo.com [PATCH] Fix jiffies_to_time[spec | val] and converse to use From: george anzinger In the current system (2.5.67) time_spec to jiffies, time_val to jiffies and the converse (jiffies to time_val and jiffies to time_spec) all use 1/HZ as the measure of a jiffie. Because of the inability of the PIT to actually generate an accurate 1/HZ interrupt, the wall clock is updated with a more accurate value (999848 nanoseconds per jiffie for HZ = 1000). This causes a 1/HZ interpretation of jiffies based timing to run faster than the wall clock, thus causing sleeps and timers to expire short of the requested time. Try, for example: time sleep 60 This patch changes the conversion routines to use the same value as the wall clock update code to do the conversions. The actual math is almost all done at compile time. The run time conversions require little if any more execution time. This patch must be applied after the patch I posted earlier today which fixed the CLOCK_MONOTONIC resolution issue. ChangeSet@1.1124.3.6, 2003-04-20 14:26:21-07:00, akpm@digeo.com [PATCH] Fix POSIX timers to give CLOCK_MONOTONIC full The POSIX CLOCK_MONOTONIC currently has only 1/HZ resolution. Further, it is tied to jiffies (i.e. is a restatment of jiffies) rather than "xtime" or the gettimeofday() clock. This patch changes CLOCK_MONOTONIC to be a restatment of gettimeofday() plus an offset to remove any clock setting activity from CLOCK_MONOTONIC. An offset is kept that represents the difference between CLOCK_MONOTONIC and gettimeofday(). This offset is updated when ever the gettimeofday() clock is set to back the clock setting change out of CLOCK_MONOTONIC (which by the standard, can not be set). With this change CLOCK_REALTIME (a direct restatement of gettimeofday()), CLOCK_MONOTONIC and gettimeofday() will all tick at the same time and with the same rate. And all will be affected by NTP adjustments (save those which actually set the time). ChangeSet@1.1124.3.5, 2003-04-20 14:26:14-07:00, akpm@digeo.com [PATCH] Fix and clean up DCACHE_REFERENCED usage From: Maneesh Soni This patch changes the way DCACHE_REFERENCED flag is used. It got messed up in dcache_rcu iterations. I hope this will be ok now. The flag was meant to be advisory flag which is used while prune_dcache() so as not to free dentries which have recently entered d_lru list. At first pass in prune_dcache the dentries marked DCACHE_REFERENCED are left with the flag reset. and they are freed in the next pass. So, now we mark the dentry as DCACHE_REFERENCED when it is first entering the d_lru list in dput() and resetthe flag in prune_dcache(). If the flag remains reset in the next call to prune_dcache(), the dentry is then freed. Also I don't think any file system have to use this flag as it is taken care by the dcache layer. The patch removes such code from a few of file systems. Moreover these filesystems were anyway doing worng thing as they were changing the flag out of dcache_lock. Changes: o dput() marks dentry DCACHE_REFERENCED when it is added to the dentry_unused list o no need to set the flag in dget, dget_locked, d_lookup as these guys anyway increments the ref count. o check the ref count in prune_dcache and use DCACHE_REFERENCED flag just for two stage aging. o remove code for setting DACACHE_REFERENCED from reiserfs, fat, xfs and exportfs.

In select_parent() and shrink_dcache_anon() we were not doing any adjustments to the nr_unused count after manipulating the dentry_unused list. Now the nr_unused count is decremented if the dentry is on dentry_unused list and is removed from there. Further in the same routines, we have to adjust the nr_unused count again if the dentry is moved to the end of d_lru list for pruning.
