writeback: Avoid softlockup when switching many inodes
[ Upstream commit 66c14dccd810d42ec5c73bb8a9177489dfd62278 ]
process_inode_switch_wbs_work() can be switching over 100 inodes to a
different cgroup. Since switching an inode requires counting all dirty &
under-writeback pages in the address space of each inode, this can take
a significant amount of time. Add a possibility to reschedule after
processing each inode to avoid softlockups.
