From e70bea5fe0e3d6355fd95674eaff5aa5a32f0564 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 11 Oct 2011 14:18:24 -0400 Subject: [PATCH] Btrfs: fix the amount of space reserved for unlink Our unlink reservations were a bit much, we were reserving 10 and I only count 8 possible items we're touching, so comment what we're reserving for and fix the count value.
