Subject: Smack: Use GFP_KERNEL for smack_parse_opts_str().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8c15d66e429afd099b66f05393527c23f85ca41c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Smack: Use GFP_KERNEL for smack_parse_opts_str().

Since smack_parse_opts_str() is calling match_strdup() which uses
GFP_KERNEL, it is safe to use GFP_KERNEL from kcalloc() which is
called by smack_parse_opts_str().
