FS_CGROUP_WRITEBACK indicates whether a file_system_type supports cgroup writeback; however, different super_blocks of the same file_system_type may or may not support cgroup writeback depending on filesystem options. This patch replaces FS_CGROUP_WRITEBACK with a kernel-internal super_block->s_flags MS_CGROUPWB. The concatenated and abbreviated name is for consistency with other MS_* flags.
Nak. As the uapi part makes it obvious the MS_ namespace is part of the userspace ABI. Please add a new in-kernel flags field instead.
