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