PATCH 1/1 include/linux/personality.h

Hi all,

the attached patch encloses the kernel-only parts of personality.h with __KERNEL__ to prevent them to be visible in userspace. This also fixes the nameclash between the macro personality() with the syscall personality() if the header file is included in an userspace program. Patch is against 2.4.21, should apply to 2.6.0-test1 equally.

Cheers,

Hannes

Don't do that, the header shouldn't be used from userspace. There's a sys/personality.h for you in glibc 2.3.
