The patch titled checkpatch: add checks for in_atomic() has been removed from the -mm tree. Its filename was checkpatch-add-checks-for-in_atomic.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: checkpatch: add checks for in_atomic() From: Andy Whitcroft <apw@xxxxxxxxxxxx> in_atomic() is not for driver use so report any such use as an ERROR. Also in_atomic() is often used to determine if we may sleep, but it is not reliable in this use model therefore strongly discourage its use.
