[PATCH] eventfs: Remove extra dget() in eventfs_create_events_dir()

[PATCH] eventfs: Remove extra dget() in eventfs_create_events_dir()

[Steven Rostedt]

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().

Fixes: 5790b1fb3d672 ("eventfs: Remove eventfs_file and just use eventfs_inode")
