From 182898192d4b720e4faeafd5b39c2cfb3b92aa21 Mon Sep 17 00:00:00 2001 From: Darren Tucker Date: Fri, 7 Jun 2019 23:47:37 +1000 Subject: Update utimensat test. POSIX specifies that when given a symlink, AT_SYMLINK_NOFOLLOW should update the symlink and not the destination. The compat code doesn't have a way to do this, so where possible it fails instead of following a symlink when explicitly asked not to. Instead of checking for an explicit failure, check that it does not update the destination, which both the real and compat implmentations should honour.
