From 300e4f8a56f263797568c95b71c949f9f02e4534 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 29 Aug 2011 14:06:00 -0400 Subject: [PATCH] Btrfs: put the block group cache after we commit the super In moving some enospc stuff around I noticed that when we unmount we are often evicting the free space cache inodes before we do our last commit. This isn't bad, but it makes us constantly have to re-read the inodes back. So instead don't evict the cache until after we do our last commit, this will make things a little less crappy and makes a future enospc change work properly.
