Subject: [PATCH] Make POSIX message queue sys_mq_open() honor umask
X-Git-Tag: v2.6.14-rc3~102
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=59175839783287d3b03f18460bb3539c69300837;p=platform%2Fkernel%2Flinux-exynos.git

[PATCH] Make POSIX message queue sys_mq_open() honor umask

We ignored umask when creating new queues via mq_open (when creating
with open() on mqueue fs it is ok of course).  According to the
specification this a bug.  This trivial patch fixes this.
