From: Ernesto A. Fernández <[email protected]> The function __gfs2_xattr_set() will return -ENODATA when called to remove a xattr that does not exist. The result is that setfacl will show an exit status of 1 when called to set only a file's mode bits (on a file with no ACLs), despite succeeding. A "No data available" error will be printed as well.
To fix this return 0 instead, except when the XATTR_REPLACE flag is set, in which case -ENODATA is appropriate. This is consistent with how most other xattr setting functions work, in other filesystems. Signed-off-by: Ernesto A.
