Subject: signal: remove jffs2_garbage_collect_thread()->allow_signal(SIGCONT)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9317bb9696566e6759203ffcaa80481b725785b3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

signal: remove jffs2_garbage_collect_thread()->allow_signal(SIGCONT)

jffs2_garbage_collect_thread() does allow_signal(SIGCONT) for no reason,
SIGCONT will wake a stopped task up even if it is ignored.
