Subject: [PATCH] Make <linux/personality.h> userspace proof
X-Git-Tag: v2.6.19-rc3~116
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=34e856e6a522a8fc0feba7497f5b05aeaa13d473;p=linux-2.6

[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.
