Subject: [PATCHSET v2 block/for-4.2/writeback] cgroup, writeback: misc updates for cgroup writeback support
Date: Tue, 16 Jun 2015 18:48:29 -0400 [thread overview]
Message-ID: <1434494912-31043-1-git-send-email-tj@kernel.org> (raw)
Hello,
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-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. Thanks.
