| |
From: "Steven Rostedt (Google)" <rostedt@goodmis.org>
The creation of the top events directory does a dget() at the end of the creation in eventfs_create_events_dir() with a comment saying the final dput() will happen when it is removed. The problem is that a dget() is already done on the dentry when it was created with tracefs_start_creating()! The dget() now just causes a memory leak of that dentry.
Remove the extra dget() as the final dput() in the deletion of the events directory actually matches the one in tracefs_start_creating().
