Please find the series which moves ext2 direct-io to use modern iomap interface. Here are some more details - 1. Patch-1: Fixes a kernel bug_on problem with ext2 dax code (found during code review and testing). 2. Patch-2: Adds a __generic_file_fsync_nolock implementation as we had discussed. 3. Patch-3 & Patch-4: Moves ext4 nojournal and ext2 to use _nolock method. 4. Patch-5: This is the main patch which moves ext2 direct-io to use iomap. (more details can be found in the patch) 5. Patch-6: Kills IOMAP_DIO_NOSYNC flag as it is not in use by any filesystem. 6. Patch-7: adds IOCB_STRINGS macro for use in trace events for better trace output of iocb flags. 7. Patch-8: Add ext2 trace point for DIO. Testing: ========= This passes ext2 "auto" group testing for fstests. There were no new failures with this patches.
