From e27d359e9b7e446190362cd5c8fe281d02194896 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 18 Mar 2012 14:07:42 -0400 Subject: SUNRPC/NFS: Add Kbuild dependencies for NFS_DEBUG/RPC_DEBUG This allows us to turn on/off the dprintk() debugging interfaces for those distributions that don't ship the 'rpcdebug' utility. It also allows us to add Kbuild dependencies. Specifically, we already know that dprintk() in general relies on CONFIG_SYSCTL. Now it turns out that the NFS dprintks depend on CONFIG_CRC32 after we added support for the filehandle hash.
