Subject: [PATCH 1/9] gluster: Drop useless has_zero_init callback
Date: Tue, 28 Apr 2020 15:28:57 -0500 [thread overview]
Message-ID: <20200428202905.770727-2-eblake@redhat.com> (raw)
In-Reply-To: <20200428202905.770727-1-eblake@redhat.com>
block.c already defaults to 0 if we don't provide a callback; there's
no need to write a callback that always fails.
