I realised I'm not entirely sure on if it's ok to do such "dangerous"
functions inside, say, tq_immediate using queue_task even ? Doesn't that
run in the interrupt context also, upon exit of the interrupt before going
I haven't followed the latest bh/tasklet/softirq development really..
IOW I want the irq to "trigger" the freeing of the iovecs but it's ok if
it's done later, as long as it's done without any races :)
BTW how does vfree cope with not walking all tasks pgd's to remove the
relevant pte's ? Doesn't that give exactly this kind of problem ? (pte's
are there despite them being deallocated)
