Subject[PATCH 1/3] drivers: nvme: target: core: fix build break
Date
Build breaks:

drivers/nvme/target/core.c: In function 'nvmet_req_alloc_sgl':
drivers/nvme/target/core.c:939:12: error: implicit declaration of \
function 'sgl_alloc'; did you mean 'bio_alloc'? \
[-Werror=implicit-function-declaration]
req->sg = sgl_alloc(req->transfer_len, GFP_KERNEL, &req->sg_cnt);
^~~~~~~~~
bio_alloc
drivers/nvme/target/core.c:939:10: warning: assignment makes pointer \
from integer without a cast [-Wint-conversion]
req->sg = sgl_alloc(req->transfer_len, GFP_KERNEL, &req->sg_cnt);
^
drivers/nvme/target/core.c: In function 'nvmet_req_free_sgl':
drivers/nvme/target/core.c:952:3: error: implicit declaration of \
function 'sgl_free'; did you mean 'ida_free'? [-Werror=implicit-function-declaration]
sgl_free(req->sg);
^~~~~~~~
ida_free

Cause:

1. missing include to <linux/scatterlist.h>
2. SGL_ALLOC needs to be enabled

Therefore adding the missing include, as well as Kconfig dependency.

This enabled target side support for the NVMe protocol, that is
it allows the Linux kernel to implement NVMe subsystems and
