* NOMMU: Lock i_mmap_mutex for access to the VMA prio listDavid Howells2012-02-24
| | | | | | | | | | | | Lock i_mmap_mutex for access to the VMA prio list to prevent concurrent access. Currently, certain parts of the mmap handling are protected by the region mutex, but not all.

That's a good question whether mem_cgroup_usage_unregister_event() should actually remove all events in one go, but nowadays it can't do any better as cftype->unregister_event callback doesn't pass any private event-associated cookie. So, let's fix the issue by simply checking for threshold->primary. FWIW, w/o the patch the following oops may be observed: BUG: unable to handle kernel NULL pointer dereference at 0000000000000004 IP: [<ffffffff810be32c>] mem_cgroup_usage_unregister_event+0x9c/0x1f0 Pid: 574, comm: kworker/0:2 Not tainted 3.3.0-rc4+ #9 Bochs Bochs RIP: 0010:[<ffffffff810be32c>] [<ffffffff810be32c>] mem_cgroup_usage_unregister_event+0x9c/0x1f0 RSP: 0018:ffff88001d0b9d60 EFLAGS: 00010246 Process kworker/0:2 (pid: 574, threadinfo ffff88001d0b8000, task ffff88001de91cc0) Call Trace: [<ffffffff8107092b>] cgroup_event_remove+0x2b/0x60 [<ffffffff8103db94>] process_one_work+0x174/0x450 [<ffffffff8103e413>] worker_thread+0x123/0x2d0 Cc: stable <stable@vger.kernel.org> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org> Acked-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Cc: Kirill A.

That means non-GPL file systems cannot exist any more unless they do not use any VFS functionality related to reading/writing as far as I can tell or at least as long as they want to implement direct i/o. Both Linus and Al (and others) have said on LKML that this breakage of the VFS API should not have happened and that the change was simply missed as it was not documented in the change logs of the patches that did those changes. This patch changes the two function exports in question to be EXPORT_SYMBOL() thus restoring the VFS API as it used to be - accessible for all modules. Christoph, who introduced the two functions and exported them GPL-only is CC-ed on this patch to give him the opportunity to object to the symbols being changed in this manner if he did indeed intend them to be GPL-only and does not want them to become available to all modules.

In the block reservation, it checks if the total number of blocks including current usage and new reservation exceed quota. In the inode reservation, it checks using the total number of inodes including only current usage without new reservation. However, this inode quota check works well since the caller of xfs_trans_dquot() always sets the argument of the number of new inode reservation to 1 or 0 and inode is reserved one by one in current xfs. To make it more general, this patch changes it to the same way as the block quota check.

A stupid regression I introduced with my previous commit to "fix" program check exceptions (brown paper bag for me), fix the cpuidle default, a bug fix for something that isn't strictly speaking a regression but some upstream changes causes it to show in lockdep now while it didn't before, and finally a trivial one for rusty to make his life easier later on removing the old cpumask cruft. ' * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc: Fix various issues with return to userspace cpuidle: Default y on powerpc pSeries powerpc: Fix program check handling when lockdep is enabled powerpc: Remove references to cpu_*_map

This is a quick set of fixes for 3.3, I'll look into a more comprehensive rework for 3.4. This fixes: - We kept interrupts soft-disabled when schedule'ing or calling do_signal when returning to userspace as a result of a hardware interrupt. - Rename do_signal to do_notify_resume like all other archs (and do_signal_pending back to do_signal, which it was before Roland changed it). - Add the missing call to key_replace_session_keyring() to do_notify_resume().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We moved all our pSeries idle loops to the cpu idle framework so we really want it to come up by default. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Whereas ENABLE_INTS leaves r3 untouched, if lockdep is enabled DISABLE_INTS calls into lockdep code and will clobber r3. That means we pass a bogus struct pt_regs* into program_check_exception() and all hell breaks loose. So load our regs pointer into r3 after we call DISABLE_INTS.

This could be bundled into one if-else-if statement, but the goto helps to clarify the 'exceptional' case. Thanks to Andreas Pape for spotting this.
