Summary
sched/debug: fix dentry leak in update_sched_domain_debugfs
Details

In the Linux kernel, the following vulnerability has been resolved:

sched/debug: fix dentry leak in updatescheddomain_debugfs

Kuyo reports that the pattern of using debugfsremove(debugfslookup()) leaks a dentry and with a hotplug stress test, the machine eventually runs out of memory.

Fix this up by using the newly created debugfslookupand_remove() call instead which properly handles the dentry reference counting logic.
