Re: INFO: rcu detected stall in shrink_dcache_parent

Infinite loop inside shrink_dcache_parent() due to lack of cond_resched(). I can reproduce this issue by running the reproducer on one CPU (using "taskset -c 0"). Reverting commit 32785c0539b7e96f ("fs/dcache.c: add cond_resched() in shrink_dentry_list()") solves this issue. #syz dup: INFO: rcu
