Subject: [PATCH v5 16/22] fsnotify: remove check that source dentry is positive
Date: Thu, 16 Jul 2020 11:42:24 +0300	[thread overview]
Message-ID: <20200716084230.30611-17-amir73il@gmail.com> (raw)
In-Reply-To: <20200716084230.30611-1-amir73il@gmail.com>

Remove the unneeded check for positive source dentry in
fsnotify_move().

fsnotify_move() hook is mostly called from vfs_rename() under
lock_rename() and vfs_rename() starts with may_delete() test that
verifies positive source dentry.  The only other caller of
fsnotify_move() - debugfs_rename() also verifies positive source.
