Hello, Changes from the last take[L] are * 0001-0006 added. * Minor changes to accomodate review points from the last round and fix compile issues w/ different config options. This patchset contains the following sixteen patches to prepare for cgroup writeback support. None of these patches introduces behavior changes. 0001-blkcg-move-block-blk-cgroup.h-to-include-linux-blk-c.patch 0002-update-CONFIG_BLK_CGROUP-dummies-in-include-linux-bl.patch 0003-blkcg-add-blkcg_root_css.patch 0004-cgroup-block-implement-task_get_css-and-use-it-in-bi.patch 0005-blkcg-implement-task_get_blkcg_css.patch 0006-blkcg-implement-bio_associate_blkcg.patch 0007-writeback-move-backing_dev_info-state-into-bdi_write.patch 0008-writeback-move-backing_dev_info-bdi_stat-into-bdi_wr.patch 0009-writeback-move-bandwidth-related-fields-from-backing.patch 0010-writeback-move-backing_dev_info-wb_lock-and-worklist.patch 0011-writeback-move-lingering-dirty-IO-lists-transfer-fro.patch 0012-writeback-reorganize-mm-backing-dev.c.patch 0013-writeback-separate-out-include-linux-backing-dev-def.patch 0014-writeback-cosmetic-change-in-account_page_dirtied.patch 0015-writeback-add-gfp-to-wb_init.patch 0016-writeback-move-inode_to_bdi-to-include-linux-backing.patch 0001-0006 are prep patches in blkcg. They're all self-explanatory. 0007-0011 move writeback related fields from bdi (backing_dev_info) to wb (bdi_writeback). Currently, one bdi embeds one wb and the separation between the two is blurry. bdi's lock protects wb's fields and fields which are closely related are scattered across the two. These five patches move all fields which are used during writeback into wb. 0012-0016 are misc prep patches in writeback. They're all rather trivial and each is self-explanatory. The patchset is on top of -mm + percpu/for-3.20 + cgroup/for-3.20 of today (2016-01-06) and is available in the following git branch. git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-cgroup-writeback-prep-20150106 diffstat follows.
