Definitely not in the second case - that one is called from inside
readdir, lookup and symlink resolution code so that could lead to deadlocks
Regarding the first case in process_sequence, that is called only from
udf_fill_super(). So there it might be safe to use GFP_KERNEL but I'm not
quite sure either... So I'd leave GFP_NOFS there.
