Subject: [PATCH v2 16/84] staging/lustre: Get rid of object update code
From: Oleg Drokin <green@...uxhacker.ru>
Object update was originally planned to be used for cross-server
updates, so nothign to do with the client. The idea was
later significantly reworked anyway so even wire structs should
not be retained.
This gets rid of update_cmd_t, UPDATE and UPDATE_REPLY rpc and
corresponding subcommands, swabbig logic and such.
