xfs: allow xfs_lock_two_inodes to take different EXCL/SHARED modes
Refactor xfs_lock_two_inodes to take separate locking modes for each inode. Specifically, this enables us to take a SHARED lock on one inode and an EXCL lock on the other. The lock class (MMAPLOCK/ILOCK) must be the same for each inode. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
