2009-12-31perf: Fix NULL deref in inheritance codePeter Zijlstra
Liming found a NULL deref when a task has a perf context but no counters when it forks. This can occur in two cases, a race during construction where the fork hits after installing the context but before the first counter gets inserted, or more reproducably, a fork after the last counter is closed (which leaves the context around).

2009-12-31perf: Pass appropriate frame pointer to dump_trace()Frederic Weisbecker
Pass the frame pointer from the regs of the interrupted path to dump_trace() while processing the stack trace. Currently, dump_trace() takes the current bp and starts the callchain from dump_trace() itself. This is wasteful because we need to walk through the entire NMI/DEBUG stack before retrieving the interrupted point. We can fix that by just using the frame pointer from the captured regs. It points exactly where we want to start.

2009-12-30mm: move sys_mmap_pgoff from util.cHugh Dickins
Move sys_mmap_pgoff() from mm/util.c to mm/mmap.c and mm/nommu.c, where we'd expect to find such code: especially now that it contains the MAP_HUGETLB handling. Revert mm/util.c to how it was in 2.6.32. This patch just ignores MAP_HUGETLB in the nommu case, as in 2.6.32, whereas 2.6.33-rc2 reported -ENOSYS. Perhaps validate_mmap_request() should reject it with -EINVAL? Add that later if necessary.

2009-12-30libsrp: fix compile failureJames Bottomley
commit 45465487897a1c6d508b14b904dc5777f7ec7e04 ("kfifo: move struct kfifo in place") caused a compile failure in ibmvscsitgt.c because it changed a pointer to kfifo in the libsrp.h structure to a direct inclusion without including <linux/kfifo.h>. The fix is simple, just add the include, but how did this happen? This change, introduced at -rc2, hardly looks like a bug fix, and it clearly didn't go through linux-next, which would have picked up this compile failure (it only occurs on ppc because of the ibm virtual scsi target).

2009-12-30ext4: Patch up how we claim metadata blocks for quota purposesTheodore Ts'o
As reported in Kernel Bugzilla #14936, commit d21cd8f triggered a BUG in the function ext4_da_update_reserve_space() found in fs/ext4/inode.c. The root cause of this BUG() was caused by the fact that ext4_calc_metadata_amount() can severely over-estimate how many metadata blocks will be needed, especially when using direct block-mapped files. In addition, it can also badly *under* estimate how much space is needed, since ext4_calc_metadata_amount() assumes that the blocks are contiguous, and this is not always true. If the application is writing blocks to a sparse file, the number of metadata blocks necessary can be severly underestimated by the functions ext4_da_reserve_space(), ext4_da_update_reserve_space() and ext4_da_release_space(). This was the cause of the dq_claim_space reports found on kerneloops.org. Unfortunately, doing this right means that we need to massively over-estimate the amount of free space needed. So in some cases we may need to force the inode to be written to disk asynchronously in to avoid spurious quota failures. http://bugzilla.kernel.org/show_bug.cgi?id=14936 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2009-12-30ksym_tracer: Fix race when incrementing countLi Zefan
We are under rcu read section but not holding the write lock, so count++ is not atomic. Use atomic64_t instead.
