* perf record: make the record options available outside perf recordTom Zanussi2010-11-10
| | | | | | | | | | | Other perf commands that invoke perf record, such as perf trace, may want to reuse the options used by perf record. This makes them non-static and renames them to avoid clashes with other 'options' variables.

* perf: Fix usages of profile_cpu in builtin-top.c to use cpu_listCorey Ashford2010-11-10
| | | | | | | | | | | | | | | | | | profile_cpu was left over from an earlier implementation that supported running perf top on a single CPU. profile_cpu was no longer set by any switch and usages of it resulted in dead code. Instead, convert the code to use cpu_list, which is set by the -C <cpu_list> option. Also improved the printing of nr_cpus and cpu_list by correcting the plurals.

| * cifs: make cifs_ioctl handle NULL filp->private_data correctlyJeff Layton2010-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 13cfb7334e made cifs_ioctl use the tlink attached to the cifsFileInfo for a filp. This ignores the case of an open directory however, which in CIFS can have a NULL private_data until a readdir is done on it. This patch re-adds the NULL pointer checks that were removed in commit 50ae28f01 and moves the setting of tcon and "caps" variables lower. Long term, a better fix would be to establish a f_op->open routine for directories that populates that field at open time, but that requires some other changes to how readdir calls are handled.

* | perf_events: Fix perf_counter_mmap() hook in mprotect()Pekka Enberg2010-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As pointed out by Linus, commit dab5855 ("perf_counter: Add mmap event hooks to mprotect()") is fundamentally wrong as mprotect_fixup() can free 'vma' due to merging. Fix the problem by moving perf_event_mmap() hook to mprotect_fixup(). Note: there's another successful return path from mprotect_fixup() if old flags equal to new flags. We don't, however, need to call perf_event_mmap() there because 'perf' already knows the VMA is executable.

Unfortunately, this no longer works, because in commit dd3932eddf (block: remove BLKDEV_IFL_WAIT), sb_issue_discard() only presents a synchronous interface, and there are times when we call ext4_free_blocks() when we are are holding a spinlock, or are otherwise in an atomic context.

In ordered mode, we need to make sure the data pages are written just in case we crash before the rename (or unlink) is committed. If the inode is being freed then when we try to igrab the inode, we end up tripping the BUG_ON at fs/ext4/page-io.c:146. To solve this problem, we need to keep track of the number of io callbacks which are pending, and avoid destroying the inode until they have all been completed. That way we don't have to bump the inode count to keep the inode from being destroyed; an approach which doesn't work because the count could have already been dropped down to zero before the inode writeback has started (at which point we're not allowed to bump the count back up to 1, since it's already started getting freed). Thanks to Dave Chinner for suggesting this approach, which is also used by XFS. kernel BUG at /scratch_space/linux-2.6/fs/ext4/page-io.c:146!

For the moment we expose some new INTC features through drivers/sh/Kconfig that the ARM platforms presently don't enable, so make it generally available.
