Subject: [PATCH 05/10] VFS: export done_path_update()
Date: Fri, 26 Aug 2022 12:10:43 +1000 [thread overview]
Message-ID: <166147984375.25420.10074672773757634204.stgit@noble.brown> (raw)
In-Reply-To: <166147828344.25420.13834885828450967910.stgit@noble.brown>
This function will be useful to nfsd, so export it. As most callers
will want "with_wq" to be true, rename the current done_path_update() to
__done_path_update() and add a new done_path_update() which sets with_wq
to true.
done_path_create_wq() is now simple enough to be "static inline"
rather than an explicit export.
