Date: Fri, 2 Mar 2012 14:56:12 -0500 From: Jeff Moyer <jmoyer@...hat.com> To: linux-fsdevel@...r.kernel.org, linux-ext4@...r.kernel.org, xfs@....sgi.com Cc: jack@...e.cz, hch@...radead.org, Jeff Moyer <jmoyer@...hat.com> Subject: [PATCH 4/7] btrfs: Use generic handlers of O_SYNC AIO DIO From: Jan Kara <jack@...e.cz> Use generic handlers to queue fsync() when AIO DIO is completed for O_SYNC file. Although we use our own bio->end_io function, we call dio_end_io() from it and thus, because we don't set any specific dio->end_io function, generic code ends up calling generic_dio_end_io() which is all what we need for proper O_SYNC AIO DIO handling.
