Hello Ingo,
patch format problem: never diff the asm/ files, diff the asm-arm/ files.
Yeah, of course, I know, I believe I made a real mess of this one ...
is it safe to do a get_user() with irqs off?
rhetorical question ;-)) I was wondering, Is it safe to use a normal spinlock here, like this? ------- 8-< ------------- spin_lock(&futex_lock); err = get_user(uval, uaddr); if ((!err) && (uval == oldval)) err = put_user(newval, uaddr); spin_unlock(&futex_lock); ------- 8-< -------------
is this method of atomic ops SMP-safe?
another rhetorical question ;-)) Nope, I already knew that, that why I mentioned that it probably only worked on UP...
