      aio: Kill unneeded kiocb members · 8bc92afc
      Kent Overstreet 提交于
      The old aio retry infrastucture needed to save the various arguments to
      to aio operations. But with the retry infrastructure gone, we can trim
      struct kiocb quite a bit.

      aio: Kill aio_rw_vect_retry() · 73a7075e
      Kent Overstreet 提交于
      This code doesn't serve any purpose anymore, since the aio retry
      infrastructure has been removed.
      
      This change should be safe because aio_read/write are also used for
      synchronous IO, and called from do_sync_read()/do_sync_write() - and
      there's no looping done in the sync case (the read and write syscalls).

      aio: Don't use ctx->tail unnecessarily · 5ffac122
      Kent Overstreet 提交于
      aio_complete() (arguably) needs to keep its own trusted copy of the tail
      pointer, but io_getevents() doesn't have to use it - it's already using
      the head pointer from the ring buffer.
      
      So convert it to use the tail from the ring buffer so it touches fewer
      cachelines and doesn't contend with the cacheline aio_complete() needs.

      aio: io_cancel() no longer returns the io_event · bec68faa
      Kent Overstreet 提交于
      Originally, io_event() was documented to return the io_event if
      cancellation succeeded - the io_event wouldn't be delivered via the ring
      buffer like it normally would.
      
      But this isn't what the implementation was actually doing; the only
      driver implementing cancellation, the usb gadget code, never returned an
      io_event in its cancel function. And aio_complete() was recently changed
      to no longer suppress event delivery if the kiocb had been cancelled.
      
      This gets rid of the unused io_event argument to kiocb_cancel() and
      kiocb->ki_cancel(), and changes io_cancel() to return -EINPROGRESS if
      kiocb->ki_cancel() returned success.
      
      Also tweak the refcounting in kiocb_cancel() to make more sense.

      aio: percpu reqs_available · e1bdd5f2
      Kent Overstreet 提交于
      See the previous patch ("aio: reqs_active -> reqs_available") for why we
      want to do this - this basically implements a per cpu allocator for
      reqs_available that doesn't actually allocate anything.
      
      Note that we need to increase the size of the ringbuffer we allocate,
      since a single thread won't necessarily be able to use all the
      reqs_available slots - some (up to about half) might be on other per cpu
      lists, unavailable for the current thread.
      
      We size the ringbuffer based on the nr_events userspace passed to
      io_setup(), so this is a slight behaviour change - but nr_events wasn't
      being used as a hard limit before, it was being rounded up to the next
      page before so this doesn't change the actual semantics.

      aio: reqs_active -> reqs_available · 34e83fc6
      Kent Overstreet 提交于
      The number of outstanding kiocbs is one of the few shared things left that
      has to be touched for every kiocb - it'd be nice to make it percpu.
      
      We can make it per cpu by treating it like an allocation problem: we have
      a maximum number of kiocbs that can be outstanding (i.e.  slots) - then we
      just allocate and free slots, and we know how to write per cpu allocators.
      
      So as prep work for that, we convert reqs_active to reqs_available.

      Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
      with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
      disable migration. But the SLUB code is relatively lockless, and the
      spin_locks there are raw_spin_locks (not converted to mutexes), thus I
      believe this bug can happen in mainline without -rt features. The -rt
      patch is just good at triggering mainline bugs ;-)
      
      Anyway, looking at where this crashed, it seems that the page variable
      can be NULL when passed to the node_match() function (which does not
      check if it is NULL). When this happens we get the above panic.
      
      As page is only used in slab_alloc() to check if the node matches, if
      it's NULL I'm assuming that we can say it doesn't and call the
      __slab_alloc() code. Is this a correct assumption?

        We had a few more in this last quota category that we might have liked

        addressed.

      llist: llist_add() can use llist_add_batch() · e9a17bd7
      Oleg Nesterov 提交于
      llist_add(new, head) can simply use llist_add_batch(new, new, head),
      no need to duplicate the code.
      
      This obviously uninlines llist_add() and to me this is a win. But we
      can make llist_add_batch() inline if this is desirable, in this case
      gcc can notice that new_first == new_last if the caller is llist_add().
