Subject: dlm: Fix dlm lock status block comment in dlm.h
Date: Tue, 07 Sep 2010 11:13:09 +0100 [thread overview]
Message-ID: <1283854389.2495.11.camel@localhost> (raw)
There is only one place in the dlm where the sb_status is set
and that is queue_cast(). Tracing back the callers of that
function shows that the listed set of return values is
out of date, so here are an updated set.
