[PATCH v2 4/8] fsdax,xfs: set the shared flag when file extent is shared

If a dax page is shared, mapread at different offsets can also trigger page fault on same dax page. So, change the flag from "cow" to "shared". And get the shared flag from filesystem when read. Signed-off-by: Shiyang Ruan --- fs/dax.c | 19 +++ fs/xfs/xfs_iomap.c |
