From 729749bb8da186e68d97d1b0439f0b1e0059c41d Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 13 Aug 2017 10:03:59 -0400 Subject: SUNRPC: Don't hold the transport lock across socket copy operations Instead add a mechanism to ensure that the request doesn't disappear from underneath us while copying from the socket. We do this by preventing xprt_release() from freeing the XDR buffers until the flag RPC_TASK_MSG_RECV has been cleared from the request.
