From 6eae8c45206733ba3a56b4f9e278774ad397b092 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 12 Jul 2016 08:36:40 -0700 Subject: [PATCH] nvme-loop: fix nvme-loop Kconfig dependencies I ran into the same problem on NVME_TARGET_RDMA now, which otherwise needs dependencies on both CONFIG_BLOCK and CONFIGFS_FS: warning: (NVME_TARGET_LOOP && NVME_TARGET_RDMA) selects NVME_TARGET which has unmet direct dependencies (BLOCK && CONFIGFS_FS) 0xA002B368 Mon Jul 11 18:00:45 CEST 2016 failed In file included from ../drivers/nvme/target/core.c:16:0: drivers/nvme/target/nvmet.h:222:14: error: field 'inline_bio' has incomplete type struct bio inline_bio; ^~~~~~~~~~ drivers/nvme/target/core.c: In function 'nvmet_async_event_work': drivers/nvme/target/core.c:98:3: error: implicit declaration of function 'kfree' [-Werror=implicit-function-declaration] kfree(aen); ^~~~~ ../drivers/nvme/target/core.c: In function 'nvmet_ns_enable': ../drivers/nvme/target/core.c:269:13: error: implicit declaration of function 'blkdev_get_by_path' [-Werror=implicit-function-declaration] ns->bdev = blkdev_get_by_path(ns->device_path, FMODE_READ | FMODE_WRITE, Folding in my patch below should address that too.
