Subject: [PATCH 05/12] VFS: export done_path_update()
Date: Tue, 14 Jun 2022 09:18:21 +1000 [thread overview]
Message-ID: <165516230198.21248.8675541854979948509.stgit@noble.brown> (raw)
In-Reply-To: <165516173293.21248.14587048046993234326.stgit@noble.brown>
This function will be be useful to nfsd, so export it.
done_path_create_wq() is now simple enough to be "static inline"
rather than an explicit export.
