Greg Kroah-Hartman c578a68ffc kernel/printk/index.c: fix memory leak with using debugfs_lookup() ... [ Upstream commit 55bf243c51 ] When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.
