Hi, Currently, AIO+DIO+O_SYNC writes are not actually sync'd (for xfs), or they are sync'd before the I/O is actually issued (everybody else). The following patch series fixes this in two parts. First, for the file systems that use the generic routines, Jan has provided some generic infrastructure to perform the syncs after the I/O is completed. Second, for those file systems which require some endio processing of their own for O_DIRECT writes (xfs and ext4), I've implemented file system specific syncing. This passes the updated xfs-tests 113 test I posted earlier, as well as all of the tests in the aio group. I tested ext3, ext4, xfs, and btrfs only. Comments, as always, are appreciated.
