From bdb9441e9c325d50b5ae17f7d3205d65b8ed2e5f Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Mon, 25 Feb 2008 23:02:48 +0100 Subject: [PATCH] lockdep: increase MAX_LOCK_DEPTH Some code paths exceed the current max lock depth (XFS), so increase this limit a bit. I looked at making this a dynamic allocated array, but we should not advocate insane lock depths, so stay with this as long as it works...
