Subject: mm, oom: remove redundant sleep in pagefault oom handler
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0fa84a4bfa2aac8c04d45351b40765d61e1fd20d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mm, oom: remove redundant sleep in pagefault oom handler

out_of_memory() will already cause current to schedule if it has not been
killed, so doing it again in pagefault_out_of_memory() is redundant.
Remove it.
