[PATCH 0/2] xfs: fix a couple of potential deadlocks

[Dave Chinner <david@fromorbit.com>]

Hi folks,

These are a couple of small fixes for lockdep enabled kernels. The
first changes the initialisation of the i_rwsem lockdep state
in the XFS code instead of in unlock_new_inode() to avoid lockdep
re-initialising the lock state after it can be found in the cache
and may have other processes waiting on the lock.

The second is adding the correct memory allocation context to
xfs_reflink_convert_cow() as it gets called in the IO path where we
hold pages locked for IO and so we can't recurse back into memory
reclaim.

Cheers,

Dave.
