| |
Add the per-directory Kconfig and Makefile, and wire them into the parent drivers/block Kconfig and Makefile so BRMR can be enabled in a kernel build.
Three Kconfig symbols are introduced:
CONFIG_BLK_DEV_BRMR (silent, selected by either side) CONFIG_BLK_DEV_BRMR_CLIENT (depends on INFINIBAND_RMR_CLIENT) CONFIG_BLK_DEV_BRMR_SERVER (depends on INFINIBAND_RMR_SERVER)
The Makefile builds two modules: brmr-client.ko and brmr-server.ko. The server side acts as a consumer of the RMR server-side IO store interface (struct rmr_srv_store_ops) to back an RMR pool with a local block device.
