Btrfs: don't use highmem for free space cache pages In order to create the free space cache concurrently with FS modifications, we need to take a few block group locks. The cache code also does kmap, which would schedule with the locks held. Instead of going through kmap_atomic, lets just use lowmem for the cache pages. Signed-off-by: Chris Mason <clm@fb.com>
