From 2e8512403525c14c9b776ce28891d09c17ada91d Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 22 Apr 2010 13:54:05 +0930 Subject: [PATCH] tdb: use tdb_nest_lock() for seqnum lock. This is pure overhead, but it centralizes the locking. Realloc (esp. as most implementations are lazy) is fast compared to the fnctl anyway.
