Max this is really too many patches now, can you please split this
up.

Can several patches be applied right now as bug fixes like:

    RDMA/rw: Fix doc typo
    RDMA/rw: Print the correct number of sig MRs
    RDMA/core: Remove unused IB_WR_REG_SIG_MR code
    RDMA/rw: Add info regarding SG count failure

??

Yes we can. Except of "RDMA/core: Remove unused IB_WR_REG_SIG_MR code".

Patches that also can be merged now are:

"IB/iser: Remove unused sig_attrs argument"

"IB/isert: Remove unused sig_attrs argument"

what is the merge plan ?

are we going to squeeze this to 5.2 or 5.3 ?

which branch should we sent the 5 patches from above ?


Thanks,
Jason
