  "message": "vfs, writeback: replace FS_CGROUP_WRITEBACK with SB_I_CGROUPWB\n\nFS_CGROUP_WRITEBACK indicates whether a file_system_type supports\ncgroup writeback; however, different super_blocks of the same\nfile_system_type may or may not support cgroup writeback depending on\nfilesystem options.  This patch replaces FS_CGROUP_WRITEBACK with a\nper-super_block flag.\n\nsuper_block-\u003es_flags carries some internal flags in the high bits but\nit\u0027s exposd to userland through uapi header and running out of space\nanyway.  This patch adds a new field super_block-\u003es_iflags to carry\nkernel-internal flags.  It is currently only used by the new\nSB_I_CGROUPWB flag whose concatenated and abbreviated name is for\nconsistency with other super_block flags.\n\next2_fill_super() is updated to set SB_I_CGROUPWB.\n\nv2: Added super_block-\u003es_iflags instead of stealing another high bit\n    from sb-\u003es_flags as suggested by Christoph and Jan.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Alexander Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: linux-fsdevel@vger.kernel.org\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: linux-ext4@vger.kernel.org\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jens Axboe \u003caxboe@fb.com\u003e\n",
