Subject: [PATCH 19/33] generic/563: fuse doesn't support cgroup-aware
 writeback accounting

From: Darrick J. Wong <djwong@...nel.org>

fuse_bdi_init disables writeback accounting on its bdi, so there's no
point in trying to measure the accounting for any block devices that the
fuse server might have open.
