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
|
|
controllers and export Linux block devices as NVMe namespaces.
|
|
You need to select at least one of the transports below to make this
|
|
functionality useful.
|
|
|
|
To configure the NVMe target you probably want to use the nvmetcli
|
|
tool from http://git.infradead.org/users/hch/nvmetcli.git.
