Subject: [PATCH 4/4] AFS: Pass an afs_call* to call->async_workfn() instead of a work_struct*
Date: Fri, 23 May 2014 13:52:29 +0100 [thread overview]
Message-ID: <20140523125229.25385.25445.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20140523125200.25385.8586.stgit@warthog.procyon.org.uk>
call->async_workfn() can take an afs_call* arg rather than a work_struct* as
the functions assigned there are now called from afs_async_workfn() which has
to call container_of() anyway.
