Subject: [PATCH v2 5/9] dax: make 'wait_table' global variable static
Date: Tue, 23 Aug 2016 16:04:15 -0600 [thread overview]
Message-ID: <20160823220419.11717-6-ross.zwisler@linux.intel.com> (raw)
In-Reply-To: <20160823220419.11717-1-ross.zwisler@linux.intel.com>
The global 'wait_table' variable is only used within fs/dax.c, and
generates the following sparse warning:
fs/dax.c:39:19: warning: symbol 'wait_table' was not declared. Should it be static?
Make it static so it has scope local to fs/dax.c, and to make sparse happy.
