From 026fec7e7c4723b5f26a753bbcad69f68c8299d4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 8 May 2017 19:01:48 +0200 Subject: sunrpc: properly type pc_decode callbacks Drop the argp argument as it can trivially be derived from the rqstp argument. With that all functions now have the same prototype, and we can remove the unsafe casting to kxdrproc_t.
