Subject: [PATCH 2/3] vfs: O_* bit numbers uniqueness check fix
Date: Tue, 16 Mar 2010 09:08:53 +0800 [thread overview]
Message-ID: <20100316011118.680475965@intel.com> (raw)
In-Reply-To: 20100316010851.331048488@intel.com
[-- Attachment #1: fcntl_init-O_RDONLY --]
[-- Type: text/plain, Size: 1108 bytes --]
Follow the comment by Eric:
Until the FMODE_ and O_ bits do not overload I think we need to check
FMODE_EXEC and FMODE_NONOTIFY (if you have that one) inside fcntl_init()
as well. I guess I'll send a patch to someone ?Al? to add FMODE_EXEC to
the list....
