Thus I removed it because at this point, it's just wrong.
Looks like there is some problems with the ABI of the syscall which makes things complicated, and is one of the reasons it wasn't hooked up yet. There's a patch coming soon that should hook it up but I don't know if it will make 2.6.19. In the meantime, we'll make sure the syscall number is reserved. It will be 258, next to mbind and currently not used. Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
