Subject: [PATCH 04/10] VFS: move dput() and mnt_drop_write() into done_path_update()
Date: Fri, 26 Aug 2022 12:10:43 +1000 [thread overview]
Message-ID: <166147984374.25420.5286418066446165003.stgit@noble.brown> (raw)
In-Reply-To: <166147828344.25420.13834885828450967910.stgit@noble.brown>
All calls to done_path_update() are followed by the same two calls, so
merge them in.
