Subject: [Cluster-devel] [PATCH] gfs2: Avoid alignment hole in struct lm_lockname
Date: Mon, 6 Mar 2017 13:27:58 -0500 (EST) [thread overview]
Message-ID: <1110213219.31149233.1488824878103.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <1488810836-11427-1-git-send-email-agruenba@redhat.com>
----- Original Message -----
| Commit 88ffbf3e03 switches to using rhashtables for glocks, hashing over
| the entire struct lm_lockname instead of its individual fields. On some
| architectures, struct lm_lockname contains a hole of uninitialized
| memory due to alignment rules, which now leads to incorrect hash values.
| Get rid of that hole.
