Subject: [PATCH v2 0/5] fuse: Interrupt-related optimizations and improvements
Date: Thu, 08 Nov 2018 12:05:14 +0300 [thread overview]
Message-ID: <154166765576.10655.15178401490817622677.stgit@localhost.localdomain> (raw)
v2: Changes in [1-2,5] patches. The biggest change is in [5],
where repeater FR_INTERRUPTED assignment is removed.
This patchset consists of several parts. Patches [1-2] optimize
likely case of request_end(), and make this function to take
fiq->waitq.lock only, when it is really needed. This improves
performance of this function completes.
Patch 3 makes request_end() to call wake_up() only for not
background requests (background requests never wait answer),
and this optimizes this function a bit more
Patches [4-5] makes code to check userspace requests correct
interrupt id to requeue (whether we've sent this interrupt).

Kirill Tkhai (5):
fuse: Kill fasync only if interrupt is queued in queue_interrupt()
fuse: Optimize request_end() by not taking fiq->waitq.lock
fuse: Wake up req->waitq of only not background requests in request_end()
fuse: Do some refactoring in fuse_dev_do_write()
fuse: Verify userspace asks to requeue interrupt that we really sent
