Subject: [PATCH 0/4 V2] iomap: Use FUA for O_DSYNC DIO writes
Date: Wed, 18 Apr 2018 14:08:24 +1000

Hi folks,

This is the latest version of the "use FUA for DIO writes" patchset
that was last posted here:

https://marc.info/?l=linux-xfs&m=152213446528167&w=2

Functionality and performance is the same as the previous version.
Changes in this version address Christoph's review comments.

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.

Cheers,

Dave.
