From 1e657bd51f313d87fbbb22d1edf625dba87ef353 Mon Sep 17 00:00:00 2001 From: Paulius Zaleckas Date: Sun, 31 Oct 2010 18:21:05 +0200 Subject: [PATCH] Regression: fix mounting NFS when NFSv3 support is not compiled Trying to mount NFS (root partition in my case) fails if CONFIG_NFS_V3 is not selected. nfs_validate_mount_data() returns EPROTONOSUPPORT, because of this check: #ifndef CONFIG_NFS_V3 if (args->version == 3) goto out_v3_not_compiled; #endif /* !CONFIG_NFS_V3 */ and args->version was always initialized to 3.
