Compared to userspace virtio-blk implementation, vhost-blk gives about 5% to 15% performance improvement. Asias He (5): aio: Export symbols and struct kiocb_batch for in kernel aio usage eventfd: Export symbol eventfd_file_create() vhost: Make vhost a separate module vhost-net: Use VHOST_NET_FEATURES for vhost-net vhost-blk: Add vhost-blk support drivers/vhost/Kconfig | 20 +- drivers/vhost/Makefile | 6 +- drivers/vhost/blk.c | 600 ++++++++++++++++++++++++++++++++++++++++++++++++ drivers/vhost/net.c | 4 +- drivers/vhost/test.c | 4 +- drivers/vhost/vhost.c | 48 ++++ drivers/vhost/vhost.h | 18 +- fs/aio.c | 37 ++- fs/eventfd.c | 1 + include/linux/aio.h | 21 ++ include/linux/vhost.h | 3 + 11 files changed, 731 insertions(+), 31 deletions(-) create mode 100644 drivers/vhost/blk.c -- 1.7.10.4
