Subject: [PATCH 03/13] ovl: ovl_check_setxattr() get rid of redundant -EOPNOTSUPP check
Date: Wed, 25 Oct 2017 15:09:25 -0400	[thread overview]
Message-ID: <1508958575-14086-4-git-send-email-vgoyal@redhat.com> (raw)
In-Reply-To: <1508958575-14086-1-git-send-email-vgoyal@redhat.com>

At mount time we check if upper supports xattr or not and set ofs->noxattr
field accordingly. But in ovl_check_setxattr() still seems to have logic
which expects that ovl_do_setxattr() can return -EOPNOTSUPP. Not sure when
and how can we hit this code. Feels redundant to me. So I am removing
this code.
