| |
Much like the other shrink_dcache_*() functions, shrink_dcache_for_umount_subtree() could run for a long time if the dcache has many entries, so an occasional "cond_resched" is needed to avoid stalls and soft-lockup warnings.
Unlike the other shrinkers, there is no cond_resched call here. So add one.
