Subject: (struct siginfo): Adjust timer info for what the kernel provides these days.
X-Git-Tag: upstream/2.30~10627^2~1388
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8eecb601ef48ada27ca1c87bf4281025472d40e1;p=external%2Fglibc.git

(struct siginfo): Adjust timer info for what the kernel provides these days.
(struct sigevent): Add _tid field.
Define SIGEV_THREAD_ID.
Remove struct __pthread_attr_s forward declaration.
