From 474279dc0f7745124fc76b474c8dc1294f8e87ce Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 1 Oct 2013 16:11:26 -0400 Subject: split __lookup_mnt() in two functions Instead of passing the direction as argument (and checking it on every step through the hash chain), just have separate __lookup_mnt() and __lookup_mnt_last(). And use the standard iterators...
