Subject: [PATCH] Make <linux/personality.h> userspace proof
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34e856e6a522a8fc0feba7497f5b05aeaa13d473;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] Make <linux/personality.h> userspace proof

<linux/personality.h> contains the constants for personality(2) but also
some defintions that are useless or even harmful in userspace such as the
personality() macro.
