Subject: [PATCH] userfaultfd: remove redundant pointer uwq
Date: Tue, 17 Jul 2018 09:08:02 +0000 [thread overview]
Message-ID: <20180717090802.18357-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Pointer uwq is being assigned but is never used hence it is
redundant and can be removed.
Cleans up clang warning:
warning: variable 'uwq' set but not used [-Wunused-but-set-variable]
