It still seems not 100% clear whether this driver will have major userspace using it. And if not, it would be very hard to support a driver when recent userspace does not use it in the end. I think a good idea for 3.6 would be to make it depend on CONFIG_STAGING. Then we don't commit to an ABI. For this, you can add a separate Kconfig and source it from drivers/staging/Kconfig. Maybe it needs to be in a separate directory drivers/vhost/staging/Kconfig. > Nicholas Bellinger (2): > vhost: Add vhost_scsi specific defines > tcm_vhost: Initial merge for vhost level target fabric driver > > Stefan Hajnoczi (2): > vhost: Separate vhost-net features from vhost features > vhost: make vhost work queue visible > > drivers/vhost/Kconfig | 6 + > drivers/vhost/Makefile | 1 + > drivers/vhost/net.c | 4 +- > drivers/vhost/tcm_vhost.c | 1609 +++++++++++++++++++++++++++++++++++++++++++++ > drivers/vhost/tcm_vhost.h | 74 ++ > drivers/vhost/test.c | 4 +- > drivers/vhost/vhost.c | 5 +- > drivers/vhost/vhost.h | 6 +- > include/linux/vhost.h | 9 + > 9 files changed, 1710 insertions(+), 8 deletions(-) > create mode 100644 drivers/vhost/tcm_vhost.c > create mode 100644 drivers/vhost/tcm_vhost.h > > -- > 1.7.2.5 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
