writeback: let balance_dirty_pages() work on the matching cgroup bdi_writeback
Currently, balance_dirty_pages() always work on bdi->wb. This patch
updates it to work on the wb (bdi_writeback) matching memcg and blkcg
of the current task as that's what the inode is being dirtied against.
balance_dirty_pages_ratelimited() now pins the current wb and passes
it to balance_dirty_pages().
As no filesystem has FS_CGROUP_WRITEBACK yet, this doesn't lead to
visible behavior differences.
v2: Updated for per-inode wb association.
