Subject: netfilter: ipset: Use kmalloc() in comment extension helper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d0d6bd61d495d271b9774a15fbea93e4875474b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

netfilter: ipset: Use kmalloc() in comment extension helper

Allocate memory with kmalloc() rather than kzalloc(): the string
is immediately initialized so it is unnecessary to zero out
the allocated memory area.

Ported from a patch proposed by Sergey Popovich <popovich_sergei@mail.ua>.
