Hammond" ll_lookup_it() checks for O_CREAT in struct lookup_intent's it_create_mode member which is nonsensical, as it_create_mode is used for file mode bits (S_IFREG, S_IRUSR, ...). Fix this by just checking for IT_CREATE in it_op and do the same in llu_lookup_it(). This will not affect the behavior of either function, since if O_CREATE (0100) is actually set in o_create_mode then IT_CREATE must have been set in it_op. In ll_atomic_open() check for O_CREAT in the open_flags parameter rather than testing mode.
