2012-10-04perf hists: Separate overhead and baseline columnsJiri Olsa
Currently the overhead and baseline columns are handled within single function and the distinction is made by 'baseline hists' pointer passed by 'struct perf_hpp::ptr'. Since hists pointer is now part of each hist_entry, it's possible to locate paired hists pointer directly from the passed struct hist_entry pointer. Also separating those 2 columns makes the code more obvious.

2012-10-04c6x: remove c6x signal.hMark Salter
The c6x signal.h includes the asm-generic version and provides a couple of extern declarations. David Howells pointed out that the externs needed to be protected by ifdef __KERNEL__. As it turns out, the externs aren't really needed since the functions are only called from asm code. So this patch gets rid of the c6x signal.h and uses just the asm-generic version.

2012-10-04firmware: use 'kernel_read()' to read firmware into kernel bufferLinus Torvalds
Fengguang correctly points out that the firmware reading should not use vfs_read(), since the buffer is in kernel space. The vfs_read() just happened to work for kernel threads, but sparse warns about the incorrect address spaces, and it's definitely incorrect and could fail for other users of the firmware loading.

2012-10-04perf tools: Complete tracepoint event namesNamhyung Kim
Currently tracepoint events cannot be completed because they contain a colon (:) character. The colon is considered as a word separator when bash completion is done - variable COMP_WORDBREAKS contains colon - so if a word being completed contains a colon it can be a problem. Recent versions of bash completion provide -n switch to _get_comp_words_by_ref and __ltrim_colon_completions functions in order to resolve this issue. Copy the latter in case not exists.

See commit message of 997c136f518c ("fs/proc/vmcore.c: add hook to read_from_oldmem() to check for non-ram pages") for details. It makes use of a new hvmop HVMOP_get_mem_type which was introduced in xen 4.2 (23298:26413986e6e0) and backported to 4.1.1. The new function is currently only enabled for reading /proc/vmcore.

2012-10-04btrfs: allow setting NOCOW for a zero sized file via ioctlDavid Sterba
Hi, the patch si simple, but it has user visible impact and I'm not quite sure how to resolve it. In short, $subj says it, chattr -C supports it and we want to use it. The conditions that acutally allow to change the NOCOW flag are clear. What if I try to set the flag on a file that is not empty? Options: 1) whole ioctl will fail, EINVAL 2.1) ioctl will succeed, the NOCOW flag will be silently removed, but the file will stay COW-ed and checksummed 2.2) ioctl will succeed, flag will not be removed and a syslog message will warn that the COW flag has not been changed 2.2.1) dtto, no syslog message Man page of chattr states that "If it is set on a file which already has data blocks, it is undefined when the blocks assigned to the file will be fully stable." Yes, it's undefined and with current implementation it'll never happen. So from this end, the user cannot expect anything. I'm trying to find a reasonable behaviour, so that a command like 'chattr -R -aijS +C' to tweak a broad set of flags in a deep directory does not fail unnecessarily and does not pollute the log. My personal preference is 2.2.1, but my dev's oppinion is skewed, not counting the fact that I know the code and otherwise would look there before consulting the documentation. The patch implements 2.2.1. david -------------8<------------------- From: David Sterba <dsterba@suse.cz> It's safe to turn off checksums for a zero sized file. http://thread.gmane.org/gmane.comp.file-systems.btrfs/18030 "We cannot switch on NODATASUM for a file that already has extents that are checksummed. The invariant here is that either all the extents or none are checksummed. Theoretically it's possible to add/remove all checksums from a given file, but it's a potentially longtime operation, the file has to be in some intermediate state where the checksums partially exist but have to be ignored (for the csum->nocsum) until the file is fully converted, this brings more special cases to extent handling, it has to survive power failure and remain consistent, and probably needs to be restarted after next mount."

2012-10-04Btrfs: fix punch hole when no extent existsJosef Bacik
I saw the warning in btrfs_drop_extent_cache where our end is less than our start while running xfstests 68 in a loop. This is because we unconditionally do drop_end = min(end, extent_end) in __btrfs_drop_extents(), even though we may not have found an extent in the range we were looking to drop. So keep track of wether or not we found something, and if we didn't just use our end. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

2012-10-04Btrfs: fix race when getting the eb out of page->privateJosef Bacik
We can race when checking wether PagePrivate is set on a page and we actually have an eb saved in the pages private pointer. We could have easily written out this page and released it in the time that we did the pagevec lookup and actually got around to looking at this page. So use mapping->private_lock to ensure we get a consistent view of the page->private pointer. This is inline with the alloc and releasepage paths which use private_lock when manipulating page->private.

2012-10-04Btrfs: do not hold the write_lock on the extent tree while loggingJosef Bacik
Dave Sterba pointed out a sleeping while atomic bug while doing fsync. This is because I'm an idiot and didn't realize that rwlock's were spin locks, so we've been holding this thing while doing allocations and such which is not good. This patch fixes this by dropping the write lock before we do anything heavy and re-acquire it when it is done. We also need to take a ref on the em's in case their corresponding pages are evicted and mark them as being logged so that releasepage does not remove them and doesn't remove them from our local list.

2012-10-04Btrfs: fix race with freeze and free space inodesJosef Bacik
So we start our freeze, somebody comes in and does an fsync() on a file where we have to commit a transaction for whatever reason, and we will deadlock because the freeze is waiting on FS_FREEZE people to stop writing to the file system, but the transaction is waiting for its free space inodes to be written out, which are in turn waiting on sb_start_intwrite while trying to write the file extents. To fix this we'll just skip the sb_start_intwrite() if we TRANS_JOIN_NOLOCK since we're being waited on by a transaction commit so we're safe wrt to freeze and this will keep us from deadlocking.

2012-10-04Btrfs: fix race in sync and freeze againJosef Bacik
I screwed this up, there is a race between checking if there is a running transaction and actually starting a transaction in sync where we could race with a freezer and get ourselves into trouble. To fix this we need to make a new join type to only do the try lock on the freeze stuff. If it fails we'll return EPERM and just return from sync.

Even though it is a co-processor, a Phi runs a full Linux environment and can support performance counters. This is just barebones support, it does not add support for interesting new features such as the SPFLT intruction that allows starting/stopping events without entering the kernel. The PMU internally is just like that of an original Pentium, but a "P6-like" MSR interface is provided.

2012-10-04UAPI: Fix the guards on various asm/unistd.h filesDavid Howells
asm-generic/unistd.h and a number of asm/unistd.h files have been given reinclusion guards that allow the guard to be overridden if __SYSCALL is defined. Unfortunately, these files define __SYSCALL and don't undefine it when they've finished with it, thus rendering the guard ineffective. The reason for this override is to allow the file to be #included multiple times with different settings on __SYSCALL for purposes like generating syscall tables. The following guards are problematic: arch/arm64/include/asm/unistd.h:#if !defined(__ASM_UNISTD_H) || defined(__SYSCALL) arch/arm64/include/asm/unistd32.h:#if !defined(__ASM_UNISTD32_H) || defined(__SYSCALL) arch/c6x/include/asm/unistd.h:#if !defined(_ASM_C6X_UNISTD_H) || defined(__SYSCALL) arch/hexagon/include/asm/unistd.h:#if !defined(_ASM_HEXAGON_UNISTD_H) || defined(__SYSCALL) arch/openrisc/include/asm/unistd.h:#if !defined(__ASM_OPENRISC_UNISTD_H) || defined(__SYSCALL) arch/score/include/asm/unistd.h:#if !defined(_ASM_SCORE_UNISTD_H) || defined(__SYSCALL) arch/tile/include/asm/unistd.h:#if !defined(_ASM_TILE_UNISTD_H) || defined(__SYSCALL) arch/unicore32/include/asm/unistd.h:#if !defined(__UNICORE_UNISTD_H__) || defined(__SYSCALL) include/asm-generic/unistd.h:#if !defined(_ASM_GENERIC_UNISTD_H) || defined(__SYSCALL) On the assumption that the guards' ineffectiveness has passed unnoticed, just remove these guards entirely.

2012-10-04crypto: x86/glue_helper - fix storing of new IV in CBC encryptionJussi Kivilinna
Glue_helper incorrectly XORs new IV over old IV at end of CBC encryption function when it should store. This causes CBC encryption to give incorrect output on multi-page encryption requests.

2012-10-04drm/i915: don't frob the vblank ts in finish_page_flipDaniel Vetter
Now that we correctly generate it, this hack is no longer required (and might actually paper over a serious bug). pageflip timestamps are sanity check in the latest version of the flip-test in intel-gpu-tools. v2: Also remove the gettimeofday(&now) which is no longer used.

2012-10-04drm/i915: call drm_handle_vblank before finish_page_flipDaniel Vetter
... since finish_page_flip needs the vblank timestamp generated in drm_handle_vblank. Somehow all the gmch platforms get it right, but all the pch platform irq handlers get is wrong. Hooray for copy& pasting! Currently this gets papered over by a gross hack in finish_page_flip. A second patch will remove that. Note that without this, the new timestamp sanity checks in flip_test occasionally get tripped up, hence the cc: stable tag.

Subsequent threads returning EBUSY from vm_insert_pfn() was not handled correctly. As a result concurrent access from new threads to mmapped data caused SIGBUS.
