From 36dd2fdb37efdab15844eb72026f8ce3aa0fb560 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 24 Sep 2009 14:58:42 -0400 Subject: [PATCH] nfs[23] tcp breakage in mount with binary options We forget to set nfs_server.protocol in tcp case when old-style binary options are passed to mount. The thing remains zero and never validated afterwards. As the result, we hit BUG in fs/nfs/client.c:588. Breakage has been introduced in NFS: Add nfs_alloc_parsed_mount_data merged yesterday...
