[PATCH] uml: switch_mm fix
Not quite, something along the lines of the patch below works correctly (and makes aio performance not suffer from multiple second delays), as skas0 mode correctly switches mm contexts, unlike TT (which should probably get nuked from the kernel now that skas0 seems to be working).
