From f485c9ee32531794e39631437fcedc82d5b8e650 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 25 Mar 2016 13:25:55 -0400 Subject: [PATCH] Btrfs: fix delalloc reservation amount tracepoint We can sometimes drop the reservation we had for our inode, so we need to remove that amount from to_reserve so that our tracepoint reports a valid amount of space.
