Subject: [PATCH 23/48] writeback: attribute stats to the matching per-cgroup bdi_writeback
Date: Mon, 23 Mar 2015 00:54:34 -0400 [thread overview]
Message-ID: <1427086499-15657-24-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1427086499-15657-1-git-send-email-tj@kernel.org>
Until now, all WB_* stats were accounted against the root wb
(bdi_writeback), now that multiple wb (bdi_writeback) support is in
place, let's attributes the stats to the respective per-cgroup wb's.
As no filesystem has FS_CGROUP_WRITEBACK yet, this doesn't lead to
visible behavior differences.
v2: Updated for per-inode wb association.
