[PATCHSET v2 block/for-4.2/writeback] cgroup, writeback: misc updates for cgroup writeback support

From: Tejun Heo
Date: Tue Jun 16 2015 - 18:49:12 EST


This is v2. The only change from the last take[L] is

* super_block->s_iflags added and MS_CGROUPWB replaced with
SB_I_CGROUPWB as suggested by Christoph and Jan.

This patchset contains the following assorted updates for the cgroup
writeback support.


0001 fixes a bug where clear FS_CGROUP_WRITEBACK flag didn't fully
disable cgroup writeback support if the filesystem code uses
wbc_init_bio() and wbc_account_io().

0002 replaces FS_CGROUP_WRITEBACK with SB_I_CGROUPWB so that cgroup
writeback support can be enabled / disabled per superblock rather than
filesystem type.

0003 updates blkio documentation with information on cgroup writeback

This patchset is on top of block/for-4.2/writeback and available in
the following git branch.

diffstat follows. Thanks.
