Hi Jason, Hi All,
this fixes the compilation problem reported by Randy Dunlap for RTRS on
rdma for-next.
Jason, am I even doing the right thing sending the fixes for the issues
reported for the for-next for RTRS/RNBD to here?

When Block Device Layer is disabled, BLK_MAX_SEGMENT_SIZE is undefined.
The rtrs is a transport library and should compile independently of the
block layer. The desired max segment size should be passed down by the
user.
Introduce max_segment_size parameter for the rtrs_clt_open() call.

Danil,
There is no need in cover letter for one patch.

I'm new to this for-next fix up procedure. What tree the commit I
should reference with the fixes line should come from? Should I split
this commit so that I can reference the commits which add separate
files in the original patchset here
https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/log/?h=for-next
? And also if I have to fix yet another issue - how do I then
reference the commit this patch creates if applied?
Thank you!

When Block Device Layer is disabled, BLK_MAX_SEGMENT_SIZE is undefined.
The rtrs is a transport library and should compile independently of the
block layer. The desired max segment size should be passed down by the
user.
Introduce max_segment_size parameter for the rtrs_clt_open() call.

NP,
You need to configure your email client to properly honor replies,
e.g. add extra blank line between your reply and the email body.
It will make your replies more clear.
Regarding fixes:
1. There should not blank line between Fixes line and SOBs.
2. You can use one Fixes line (use latest).
3. Patches are usually divided for logical units.

Yes, I will take them.

Hi Jason,
Does your "for-next" feed into linux-next?
I am still seeing this build error today (linux-next 20200521).
thanks.
