FAT12 entry is 12bits, so it needs 2 phase to update the value. And writer and reader access it without any lock, so reader can get the half updated value. This fixes the long standing race condition by adding a global spinlock to only FAT12 for avoiding any impact against FAT16/32.

This is a patch that speeds up statfs. It is very simple - the "overhead" calculation, which takes a huge amount of time for large filesystems, never changes unless the size of the filesystem itself changes. That means we can store it in memory and only recalculate if the filesystem has been resized (almost never). It also fixes a minor problem that we never update the on-disk superblock free blocks/inodes counts until the filesystem is unmounted. While not fatal, we may as well update that on disk when we have the information, and it makes things like debugfs and dumpe2fs report a bit more accurate info.

Optimize integer-to-string conversion in vsprintf.c for base 10. This is by far the most used conversion, and in some use cases it impacts performance. For example, top reads /proc/$PID/stat for every process, and with 4000 processes decimal conversion alone takes noticeable time. Using code from http://www.cs.uiowa.edu/~jones/bcd/decimal.html (with permission from the author, Douglas W. Jones) binary-to-decimal-string conversion is done in groups of five digits at once, using only additions/subtractions/shifts (with -O2; -Os throws in some multiply instructions). On i386 arch gcc 4.1.2 -O2 generates ~500 bytes of code. This patch is run tested. Userspace benchmark/test is also attached. I tested it on PIII and AMD64 and new code is generally ~2.5 times faster. On AMD64: # ./vsprintf_verify-O2 Original decimal conv: .......... 151 ns per iteration Patched decimal conv: .......... 62 ns per iteration Testing correctness 12895992590592 ok... [Ctrl-C] # ./vsprintf_verify-O2 Original decimal conv: .......... 151 ns per iteration Patched decimal conv: .......... 62 ns per iteration Testing correctness 26025406464 ok... [Ctrl-C] More realistic test: top from busybox project was modified to report how many us it took to scan /proc (this does not account any processing done after that, like sorting process list), and then I test it with 4000 processes: #!/bin/sh i=4000 while test $i != 0; do sleep 30 & let i-- done busybox top -b -n3 >/dev/null on unpatched kernel: top: 4120 processes took 102864 microseconds to scan top: 4120 processes took 91757 microseconds to scan top: 4120 processes took 92517 microseconds to scan top: 4120 processes took 92581 microseconds to scan on patched kernel: top: 4120 processes took 75460 microseconds to scan top: 4120 processes took 66451 microseconds to scan top: 4120 processes took 67267 microseconds to scan top: 4120 processes took 67618 microseconds to scan The speedup comes from much faster generation of /proc/PID/stat by sprintf() calls inside the kernel.

* There is no point in having full "0...9a...z" constant vector, if we use only "0...9a...f" (and "x" for "0x"). * Post-decrement usually needs a few more instructions, so use pre decrement instead where makes sense: - while (i < precision--) { + while (i <= --precision) { * if base != 10 (=> base 8 or 16), we can avoid using division in a loop and use mask/shift, obtaining much faster conversion. (More complex optimization for base 10 case is in the second patch). Overall, size vsprintf.o shows ~80 bytes smaller text section with this patch applied.

In drivers/pnp/isapnp/core.c::isapnp_read_tag() there is a test of 'type' being == 0 a bit down in the function. That test doesn't make any sense. If 'type' could indeed be NULL, then the test happens way too late as we'd already have tried to dereference the pointer earlier and looking at the callers it also turns out that there is no way type can ever actually be NULL. So the test is completely pointless and should just be removed.

kernel/printk.c: document possible deadlock against scheduler The printk's comment states that it can be called from every context, which might lead to false illusion that it could be called from everywhere without any restrictions.

Change cancel_work_sync() and cancel_delayed_work_sync() to return a boolean indicating whether the work was actually cancelled. A zero return value means that the work was not pending/queued. Without that kind of change it is not possible to avoid flush_workqueue() sometimes, see the next patch as an example. Also, this patch unifies both functions and kills the (unlikely) busy-wait loop.

由 Oleg Nesterov 提交于
Imho, the current naming of cancel_xxx workqueue functions is very confusing. cancel_delayed_work() cancel_rearming_delayed_work() cancel_rearming_delayed_workqueue() // obsolete cancel_work_sync() This looks as if the first 2 functions differ in "type" of their argument which is not true any longer, nowadays the difference is the behaviour. The semantics of cancel_rearming_delayed_work(dwork) was changed significantly, it doesn't require that dwork rearms itself, and cancels dwork synchronously. Rename it to cancel_delayed_work_sync(). This matches cancel_delayed_work() and cancel_work_sync(). Re-create cancel_rearming_delayed_work() as a simple inline obsolete wrapper, like cancel_rearming_delayed_workqueue().

The UMSDOS filesystem was removed back in 2.6.11, but some tiny bits stuck around. This patch removes the few remaining leftovers. The only things left behind after this are the entries in the CREDITS file and the ioctl number in Documentation/ioctl-number.txt as documentation. This third (hopefully final) version of the patch doesn't edit the arch/um/config.release file, since Jeff Dike pointed out to me that it should die completely, and asked me to remove it from my patch as he'll send in a seperate patch removing the file completely.

由 Heiko Carstens 提交于
The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by: NJeremy Fitzhardinge <jeremy@goop.org> Acked-by: NHaavard Skinnemoen <hskinnemoen@atmel.com> Cc: Andi Kleen <ak@suse.de> Cc: Kyle McMartin <kyle@parisc-linux.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Paul Mundt <lethal@linux-sh.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
