NeilBrown b41eeef14d knfsd: avoid Oops if buggy userspace performs confusing filehandle->dentry mapping ... When a lookup request arrives, nfsd uses information provided by userspace (mountd) to find the right filesystem. It then assumes that the same filehandle type as the incoming filehandle can be used to create an outgoing filehandle. However if mountd is buggy, or maybe just being creative, the filesystem may not support that filesystem type, and the kernel could oops, particularly if 'ex_uuid' is NULL but a FSID_UUID* filehandle type is used. So add some proper checking that the fsid version/type from the incoming filehandle is actually supportable, and ignore that information if it isn't supportable.
