From 88d3a5aaf6171d9a222961837ba329b850f140e3 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 13 Jan 2016 13:21:20 -0500 Subject: [PATCH] Btrfs: add transaction space reservation tracepoints There are a few places where we add to trans->bytes_reserved but don't have the corresponding trace point. With these added my tool no longer sees transaction leaks.
