Subject: [PATCH dlm/next 3/8] dlm: use is_master() on checks if we are the master
Date: Mon,  3 Jun 2024 17:55:53 -0400	[thread overview]
Message-ID: <20240603215558.2722969-4-aahringo@redhat.com> (raw)
In-Reply-To: <20240603215558.2722969-1-aahringo@redhat.com>

There are checks if we are the master or not done by
"r->res_master_nodeid == dlm_our_nodeid()" or unequal to check if we are
not the master. There is a helper function is_master() for doing this
kind of check. This patch replaces several checks of those by using the
helper instead of using the mentioned condition check.
