From b1983cd897ec06080ec4884989c6a3f1e7ee7dce Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 4 May 2013 15:18:53 -0400 Subject: [PATCH] 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.
