From 1ebfc66b2c145289d1e1314e8415d9e3c6f405ae Mon Sep 17 00:00:00 2001 From: Volker Lendecke Date: Mon, 10 Mar 2008 21:08:29 +0100 Subject: Use a separate tdb for mutexes Another preparation to convert secrets.c to dbwrap: The dbwrap API does not provide a sane tdb_lock_with_timeout abstraction. In the clustered case the DC mutex is needed per-node anyway, so it is perfectly fine to use a local mutex only.
