* [PATCH] Decrapify asm-generic/local.hKyle McMartin2006-03-281-71/+9Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that Christoph Lameter's atomic_long_t support is merged in mainline, might as well convert asm-generic/local.h to use it, so the same code can be used for both sizes of 32 and 64-bit unsigned longs. akpm sayeth: Q: Is there any particular reason why these routines weren't simply implemented with local_save/restore_flags, if they are only meant to guarantee atomicity to the local cpu? I'm sure on most platforms this would be more efficient than using an atomic... A: The whole _point_ of local_t is to avoid local_irq_disable(). It's designed to exploit the fact that many CPUs can do incs and decs in a way which is atomic wrt local interrupts, but not atomic wrt SMP. But this patch makes sense, because asm-generic/local.h is just a fallback implementation for architectures which either cannot perform these local-irq-atomic operations, or its maintainers haven't yet got around to implementing them. We need more work done on local_t in the 2.6.17 timeframe - they're defined as unsigned long, but some architectures implement them as signed long.

* [PATCH] RTC: Remove RTC UIP synchronization on x86Matt Mackall2006-03-281-14/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading the CMOS clock on x86 and some other arches currently takes up to one second because it synchronizes with the CMOS second tick-over. This delay shows up at boot time as well a resume time. This is the currently the most substantial boot time delay for machines that are working towards instant-on capability. Also, a quick back of the envelope calculation (.5sec * 2M users * 1 boot a day * 10 years) suggests it has cost Linux users in the neighborhood of a million man-hours. An earlier thread on this topic is here: http://groups.google.com/group/linux.kernel/browse_frm/thread/8a24255215ff6151/2aa97e66a977653d?hl=en&lr=&ie=UTF-8&rnum=1&prev=/groups%3Fhl%3Den%26lr%3D%26ie%3DUTF-8%26selm%3D1To2R-2S7-11%40gated-at.bofh.it#2aa97e66a977653d ..from which the consensus seems to be that it's no longer desirable. In my view, there are basically four cases to consider: 1) networked, need precise walltime: use NTP 2) networked, don't need precise walltime: use NTP anyway 3) not networked, don't need sub-second precision walltime: don't care 4) not networked, need sub-second precision walltime: get a network or a radio time source because RTC isn't good enough anyway So this patch series simply removes the synchronization in favor of a simple seqlock-like approach using the seconds value. Note that for purposes of timer accuracy on wakeup, this patch will cause us to fire timers up to one second late. But as the current timer resume code will already sync once (or more!), it's no worse for short timers. Signed-off-by: Matt Mackall <mpm@selenic.com> Cc: Andi Kleen <ak@muc.de> Cc: "David S.

Unfortunately, most system tools that work with these numbers that are exported in /proc/diskstats including iostat read these numbers into unsigned longs. This works fine on 32b platforms and when the number of IO transactions are small on 64b platforms. However, when the numbers wrap on 64b platforms & you read the numbers into unsigned longs, and compare the numbers to previous readings, then you get an unsigned representation of a negative number. This looks like a very large 64b number & gives you bizarre readouts in iostat: ilc4: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util ilc4: sda 5.50 0.00 143.96 0.00 307496983987862656.00 0.00 153748491993931328.00 0.00 2136028725038430.00 7.94 55.12 5.59 80.42 Though fixing iostat in user space is possible, and a quick survey indicates that several other similar tools also use unsigned longs when processing /proc/diskstats. Therefore, it seems like a better approach would be to extend the length of the disk_stats structure on 64b architectures to 64b. The following patch does that. It should not affect the operation on 32b platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | When retrying a write due to barrier failure, we don't reset 'remaining', so it goes negative and never hits 0 again.

* | | [PATCH] md: Fix md grow/size code to correctly find the maximum available spaceNeilBrown2006-03-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An md array can be asked to change the amount of each device that it is using, and in particular can be asked to use the maximum available space. This currently only works if the first device is not larger than the rest. As 'size' gets changed and so 'fit' becomes wrong. So check if a 'fit' is required early and don't corrupt it.

* | | [PATCH] md: Remove bi_end_io call out from under a spinlockNeilBrown2006-03-271-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | raid5 overloads bi_phys_segments to count the number of blocks that the request was broken in to so that it knows when the bio is completely handled. Accessing this must always be done under a spinlock. In one case we also call bi_end_io under that spinlock, which probably isn't ideal as bi_end_io could be expensive (even though it isn't allowed to sleep). So we reducde the range of the spinlock to just accessing bi_phys_segments.
