From 8c4ed633e65d0bd0a25d45aad9b4646e3236cad7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 30 Oct 2008 16:55:13 +1100 Subject: [XFS] make btree tracing generic Make the existing bmap btree tracing generic so that it applies to all btree types. Some fragments lifted from a patch by Dave Chinner.
