Subject: [PATCH] gfs2: select CONFIG_LIBCRC32C
Date:   Fri,  2 Feb 2018 16:43:56 +0100
Message-Id: <20180202154403.1605622-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The new crc32c logic in gfs2_log_header_v2 causes a link
error without libcrc32c:

ERROR: "crc32c" [fs/gfs2/gfs2.ko] undefined!

While the original patch selected CONFIG_CRYPTO_CRC32C to deal
with this issue, it turned out to be the wrong symbol.

Fixes: c1696fb85d33 ("GFS2: Introduce new gfs2_log_header_v2")
