Subject: NLM: don't use CLONE_SIGHAND in nlmclnt_recovery
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=550facd138d8f6b0ca683c1e894b5cd0f381cb63;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

NLM: don't use CLONE_SIGHAND in nlmclnt_recovery

reclaimer() calls allow_signal() which plays with parent process's ->sighand.
