Fix a possible deadlock on inotify_mutex, reported by lockdep.
inotify_inode_queue_event() => take inotify_mutex => kernel_event() =>
kmalloc() => SLOB => alloc_pages_node() => page reclaim => slab reclaim =>
dcache reclaim => inotify_inode_is_dead => take inotify_mutex => deadlock
The actual deadlock may not happen because the inode was grabbed at
inotify_add_watch(). But the GFP_KERNEL here is unsound and not
consistent with the other two GFP_NOFS inside the same function.

I really didn't forget this, but I can't figure out how to recreate it,
so I don't know if my logic in the patch is sound. The patch certainly
will shut up the complaint.
We can only hit this inotify cleanup path if the i_nlink = 0. I can't
find a way to leave the dentry around for memory pressure to clean up
later, but have the n_link = 0. On ext* the inode is kicked out as soon
as the last close on all open fds for an inode which has been unlinked.
I tried attaching an inotify watch to an NFS or CIFS inode, deleting the
inode on another node, and then putting the first machine under memory
pressure. I'm not sure why, but the dentry or inode in question were
never evicted so I didn't hit this path either....
I know the patch will shut up the problem, but since I can't figure out
by looking at the code a path to reproduce I don't really feel 100%
confident that it is correct....
-Eric
inotify: lockdep annotation when watch being removed
From: Eric Paris <eparis@redhat.com>
When a dentry is being evicted from memory pressure, if the inode associated
with that dentry has i_nlink == 0 we are going to drop all of the watches and
kick everything out. Lockdep complains that previously holding inotify_mutex
we did a __GFP_FS allocation and now __GFP_FS reclaim is taking that lock.
There is no deadlock or danger, since we know on this code path we are
actually cleaning up and evicting everything. So we move the lock into a new
class for clean up.

I really didn't forget this, but I can't figure out how to recreate it,
so I don't know if my logic in the patch is sound. The patch certainly
will shut up the complaint.
We can only hit this inotify cleanup path if the i_nlink = 0. I can't
find a way to leave the dentry around for memory pressure to clean up
later, but have the n_link = 0. On ext* the inode is kicked out as soon
as the last close on all open fds for an inode which has been unlinked.
I tried attaching an inotify watch to an NFS or CIFS inode, deleting the
inode on another node, and then putting the first machine under memory
pressure. I'm not sure why, but the dentry or inode in question were
never evicted so I didn't hit this path either....
I know the patch will shut up the problem, but since I can't figure out
by looking at the code a path to reproduce I don't really feel 100%
confident that it is correct....

inotify: lockdep annotation when watch being removed
From: Eric Paris <eparis@redhat.com>
When a dentry is being evicted from memory pressure, if the inode associated
with that dentry has i_nlink == 0 we are going to drop all of the watches and
kick everything out. Lockdep complains that previously holding inotify_mutex
we did a __GFP_FS allocation and now __GFP_FS reclaim is taking that lock.
There is no deadlock or danger, since we know on this code path we are
actually cleaning up and evicting everything. So we move the lock into a new
class for clean up.

I can reproduce the bug and hence confirm that this patch works, so

kernel_event() has side by side kmem_cache_alloc(GFP_NOFS)

Hmmmmm, maybe we need to move the mutex_init(&inode->inotify_mutex) call
from inode_init_once to inode_init_always so those inodes/locks that we
moved into the new class will get put back in the old class when they
are reused...

Do you think we should merge the GFP_NOFS workaround for 2.6.30 and
fix all up nicely for 2.6.31?
GFP_NOFS isn't all that bad, really - it will work sufficiently well.
Being able to switch it over to GFP_KERNEL later on is a pretty minor
optimisation. But it would be bad of us to simply forget about it, so I'd
probably end up retaining a switch-back-to-GFP_KERNEL patch in -mm with
which to periodically harrass you guys ;)

I queued that as an incremental to Wu Fengguang's patch, because

So this is a completely different message than the original report, and
one that is kind of cool and interesting. I think it could be triggered
today. Again I think it's a false positive, since the inodes in
question are being kicked out of kernel because the fs is being
unmounted, but I'll poke someone to make sure I understand what lockdep
is telling me and we can shut this one up too if we care....

Hmm, shouldn't this go in the common inode freeing path rather than
a hack in inotify?
Also, I think linux-fsdevel should be cc'ed on anything like this
(which I added)
