Re: INFO: rcu detected stall in _raw_spin_unlock




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.
