I've had a first pass at this now, see https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=arm-kill-set_fs There are a couple of things in there that ended up uglier than I was hoping for, and it's completely untested beyond compilation. Is this roughly what you had in mind? I can do some testing then and post it to the Arm mailing list. Arnd
