Subject: writeback: don't use schedule_timeout() without setting runstate
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3542a5c0de3d5b33227214a692bf9b12e249078e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

writeback: don't use schedule_timeout() without setting runstate

Just use schedule_timeout_interruptible(), saves a call to
set_current_state().
