From 0fa800fbd549736dfdc1d7761f87e33dc8cd973b Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 11 Jan 2010 11:47:46 +0000 Subject: xfs: Add trace points for per-ag refcount debugging. Uninline xfs_perag_{get,put} so that tracepoints can be inserted into them to speed debugging of reference count problems.
