Hi folks,
Version 3 of the FUA for O-DSYNC patchset. This version fixes bugs
found in the previous version. Functionality is otherwise the same
as described in the first version:
https://marc.info/?l=linux-xfs&m=152213446528167&w=2
Version 3:
- fixed O_SYNC behaviour as noticed by Jan Kara
- fixed use after free on IO completion due
iomap_dio_complete_work() simplification added in version 2. Found
by KASAN when running xfstests.
Version 2:
- Fixed comment typos in first patch
- simplified iomap_dio_complete_work()
- changed IOMAP_DIO_WRITE_SYNC to IOMAP_DIO_NEED_SYNC
- split blk_queue_fua() into it's own patch
- fixed formatting issue in last patch
- update bio->io_opf directly rather than use bio_set_op_attrs()
- Updated comment to mention we try to use FUA optimistically.
