From: John L. Hammond Date: Tue, 3 Dec 2013 13:58:45 +0000 (+0800) Subject: staging/lustre/llite: don't check for O_CREAT in it_create_mode X-Git-Tag: firefly_0821_release~176^2~4489^2~676 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1e8a576eb38f23e55ed88e4e8e2b35ccb43cfb7f;p=firefly-linux-kernel-4.4.55.git staging/lustre/llite: don't check for O_CREAT in it_create_mode 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. 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.
