create_mnt_ns: unidiomatic use of list_add()
while list_add(A, B) and list_add(B, A) are equivalent when both A and B are guaranteed to be empty, the usual idiom is list_add(what, where), not the other way round... Not a bug per se, but only by accident and it makes RTFS harder for no good reason. Spotted-by: Rajat Sharma <fs.rajat@gmail.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
