From 7e2355ba1a11649f0b212a29fdb9f47476f1248e Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 11 May 2011 12:25:37 -0400 Subject: [PATCH] Btrfs: don't look at the extent buffer level 3 times in a row We have a bit of debugging in btrfs_search_slot to make sure the level of the cow block is the same as the original block we were cow'ing. I don't think I've ever seen this tripped, so kill it. This saves us 2 kmap's per level in our search.
