-Subject: [PATCH] ubifs: Drop softlimit and delta fields from struct ubifs_wbuf
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Values of these fields are set during init and never modified. They are
-used (read) in a single function only. There isn't really any reason to
-keep them in a struct. It only makes struct just a bit bigger without
-any visible gain.
