Hi Everyone,
I would like to inform you that conversion from tasklets to workqueues are now
merged into bluetooth-next. Those patches move all Bluetooth processing to the
process context, thus it makes the manipulation of Bluetooth data much more
easier. We were able to make locking more sane, and some of them were even
changed to use RCU.
In the end only the rx/tx works were kept at the hdev->workqueue, all others
works were moved to the system workqueue. In the future, if the need arises we
can create a global workqueue for random works.
Some work is still missing, like:
- make sure SCO, SMP, BNEP and HIDP are working.
- work on mod_delayed_queue() to improve our timers usage
- proper chan_put/chan_hold in l2cap_set_timer/clear_timer
- use GFP_KERNEL where possible
- Look for improvements in the locking system
- some other places needs move to workqueue, like the security timer in l2cap
I also would like to ask you to rebase your code on top of this and re-submit
it to the mailing list. I know this a is a bit painful now, but it will help
development a lot from now on. If we move fast here we still can make 3.3 for
most of your patches. I'm waiting your patches!
And please, test this. We need to make sure we are not breaking anything here.
These are the workqueue patches btw:
