[PATCH v7 6/6] xfs: disable map_sync for async flush

2019-04-25 Thread Pankaj Gupta
Dont support 'MAP_SYNC' with non-DAX files and DAX files with asynchronous dax_device. Virtio pmem provides asynchronous host page cache flush mechanism. We don't support 'MAP_SYNC' with virtio pmem and xfs. Signed-off-by: Pankaj Gupta --- fs/xfs/xfs_file.c | 9 ++--- 1 file changed, 6 inser
