The patch titled sched: remove long deprecated CLONE_STOPPED flag has been removed from the -mm tree. Its filename was sched-remove-long-deprecated-clone_stopped-flag.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: sched: remove long deprecated CLONE_STOPPED flag From: Dave Jones <davej@xxxxxxxxxx> This warning was added in commit bdff746a3915 ("clone: prepare to recycle CLONE_STOPPED") three years ago. 2.6.26 came and went. As far as I know, no-one is actually using CLONE_STOPPED.
