Message-ID: <155795391416.28355.16992553812228405622.stgit@warthog.procyon.org.uk>
Date: Wed, 15 May 2019 21:58:34 +0100
From: David Howells <dhowells@...hat.com>
To: linux-afs@...ts.infradead.org
Cc: dhowells@...hat.com, linux-kernel@...r.kernel.org
Subject: [PATCH 02/12] afs: Get rid of afs_call::reply[]
Replace the afs_call::reply[] array with a bunch of typed members so that
the compiler can use type-checking on them. It's also easier for the eye
to see what's going on.
