Thw open_tree and move_mount syscalls take names from the user, so add the __user to these to ensure the following warnings from sparse are fixed: fs/namespace.c:2392:35: warning: incorrect type in argument 2 (different address spaces) fs/namespace.c:2392:35: expected char const [noderef] <asn:1> *name fs/namespace.c:2392:35: got char const *filename fs/namespace.c:3541:38: warning: incorrect type in argument 2 (different address spaces) fs/namespace.c:3541:38: expected char const [noderef] <asn:1> *name fs/namespace.c:3541:38: got char const *from_pathname fs/namespace.c:3550:36: warning: incorrect type in argument 2 (different address spaces) fs/namespace.c:3550:36: expected char const [noderef] <asn:1> *name fs/namespace.c:3550:36: got char const *to_pathname Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
