During a discussion in 2011 nobody recalled why FMR was not used for
non-page aligned buffers (see also

for such buffers. For the reason why the srp_map_fmr() function needs
to be modified, see also patch "IB/srp: rework mapping engine to use
multiple FMR entries" (commit ID 8f26c9ff9cd0; January 2011).

Hi Bart,
Just wanted to confirm that this was tested with FMR and non-aligned IO.
(the change log doesn't say it).
Hello Sagi,
This patch series has been tested with FMR and I/O buffers that were not
aligned to a page boundary by setting the ib_srp kernel module parameter
prefer_fr to 0.
Bart.
