[PATCH] nfsd4_lock() returns bogus values to clients
missing nfserrno() in default case of a switch by return value of posix_lock_file(); as the result we send negative host-endian to clients that expect positive network-endian, preferably mentioned in RFC... BTW, that case is not impossible - posix_lock_file() can return -ENOLCK and we do not handle that one explicitly.
