From 70d45cdb664390a5573c05f1eecc8432dcc6581b Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 16 Jun 2015 01:56:23 -0400 Subject: ufs: don't touch mtime/ctime of directory being moved See "ext2: Do not update mtime of a moved directory" (and followup in "ext2: fix unbalanced kmap()/kunmap()") for background; this is UFS equivalent - the same problem exists here.
