Subject: [PATCH v3 06/10] debugfs: simplify __debugfs_remove_file()
Date: Sun, 26 May 2019 17:34:07 +0300	[thread overview]
Message-ID: <20190526143411.11244-7-amir73il@gmail.com> (raw)
In-Reply-To: <20190526143411.11244-1-amir73il@gmail.com>

Move simple_unlink()+d_delete() from __debugfs_remove_file() into
caller __debugfs_remove() and rename helper for post remove file to
__debugfs_file_removed().

This will simplify adding fsnotify_unlink() hook.
