The original size class loading logic was totally broken.

Patch 1 fixes it.
Patch 2 adds sysfs visibility to size classes so that we don't mess up
this badly in the future (and can test it in xfstests now).

Boris Burkov (2):
  btrfs: fix size class loading logic
  btrfs: add size class stats to sysfs
