Matthew Bobrowski 548feebec7 ext4: update direct I/O read lock pattern for IOCB_NOWAIT ... This patch updates the lock pattern in ext4_direct_IO_read() to not block on inode lock in cases of IOCB_NOWAIT direct I/O reads. The locking condition implemented here is similar to that of 942491c9e6 ("xfs: fix AIM7 regression").
