Fact that you dropped my sane patches aside and decided to write a much larger series aside, user-mode Linux in upstream is broken. This means that any user who does: $ ARCH=um make defconfig $ ARCH=um make will end up with a *broken* Linux _today_. Unless the user is living in the Stone Age with a 32-bit computer, this is what she will see when she attempts to boot up Linux: $ file linux linux: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, not stripped $ ./linux ubd0=busybox-rootfs [...] Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

When I rebase my original patches (exactly 2 small independent patches) onto the new upstream, stuff works as usual. If you're not convinced, try the um-build branch from https://github.com/artagnon/linux for yourself. Are you against accepting good patches and stalling work? What is your plan exactly? Annoyed, Ram
