[PATCH 3/5] vhost: Make vhost a separate module
Currently, vhost-net is the only consumer of vhost infrastructure. So
vhost infrastructure and vhost-net driver are in a single module.
Separating this as a vhost.ko module and a vhost-net.ko module makes it
is easier to share code with other vhost drivers, e.g. vhost-blk.ko,
tcm-vhost.ko.

[PATCH 0/5] Add vhost-blk support
Hi folks,
This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk
device accelerator. Compared to userspace virtio-blk implementation, vhost-blk
gives about 5% to 15% performance improvement.

[PATCH] vhost-blk: Add vhost-blk support v2
vhost-blk is an in-kernel virito-blk device accelerator.
Due to lack of proper in-kernel AIO interface, this version converts
guest's I/O request to bio and use submit_bio() to submit I/O directly.
So this version any supports raw block device as guest's disk image,
e.g. /dev/sda, /dev/ram0. We can add file based image support to
vhost-blk once we have in-kernel AIO interface. There are

[PATCH 1/5] fs: allow short direct-io reads to be completed via buffered IO V2
V1->V2: Check to see if our current ppos is >= i_size after a short DIO read,
just in case it was actually a short read and we need to just return.
This is similar to what already happens in the write case. If we have a short
read while doing O_DIRECT, instead of just returning, fallthrough and try to
read the rest via buffered IO. BTRFS needs this because if we encounter a

[PATCH 1/1] Ocfs2: Teach 'coherency=full' O_DIRECT writes to correctly up_read i_alloc_sem.
Former logic of ocfs2_file_aio_write() was a bit stricky to unlock the rw_lock
and i_alloc_sem, by using some private bits in struct 'iocb' to communite with
ocfs2_dio_end_io(), it did work before we introduce the patch of supporting
'coherency=full,buffered' option, since rw_lock and i_alloc_sem were never
acquired both at the same time, no mattar we doing buffered or direct IO or

[PATCH 0/9] remove i_alloc_sem V2
i_alloc_sem has always been a bit of an odd "lock". It''s the only remaining
rw_semaphore that can be released by a different thread than the one that
locked it, and it''s use case in the core direct I/O code is more like a
counter given that the writers already have external serialization.
This series removes it in favour of a simpler counter scheme, thus getting
