From: Julian Wiedmann Date: Tue, 20 Mar 2018 06:59:13 +0000 (+0100) Subject: s390/qeth: when thread completes, wake up all waiters X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dd5ec7314030ed1e536244e8be1cbed8188616ac;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git s390/qeth: when thread completes, wake up all waiters [ Upstream commit 1063e432bb45be209427ed3f1ca3908e4aa3c7d7 ] qeth_wait_for_threads() is potentially called by multiple users, make sure to notify all of them after qeth_clear_thread_running_bit() adjusted the thread_running_mask. With no timeout, callers would otherwise stall. Signed-off-by: Julian Wiedmann Signed-off-by: David S.
