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-writeback-do-foreign-inode-detection-iff-cgroup-writ.patch 0002-vfs-writeback-replace-FS_CGROUP_WRITEBACK-with-SB_I_.patch 0003-writeback-blkio-add-documentation-for-cgroup-writeba.patch 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 support. This patchset is on top of block/for-4.2/writeback and available in the following git branch. git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-cgroup-writeback-updates diffstat follows.
