Subject: ____call_usermodehelper: don't flush_signals()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c93465181fed0f8f5942a41108943dadea0aa345;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

____call_usermodehelper: don't flush_signals()

____call_usermodehelper() has no reason for flush_signals().  It is a fresh
forked process which is going to exec a user-space application or exit on
failure.
