Subject: [PATCH] Don't print per-cpu vm stats for offline cpus.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6b482c6779daaa893b277fc9b70767a7c2e7c5eb;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] Don't print per-cpu vm stats for offline cpus.

I just hit a page allocation error on a kernel configured to support
64 CPUs.  It spewed 60 completely useless unnecessary lines of info.
