### Description

In the Linux kernel, the following vulnerability has been resolved:sched/debug: fix dentry leak in update_sched_domain_debugfsKuyo reports that the pattern of using debugfs_remove(debugfs_lookup())leaks a dentry and with a hotplug stress test, the machine eventuallyruns out of memory.Fix this up by using the newly created debugfs_lookup_and_remove() callinstead which properly handles the dentry reference counting logic.
