spiechurski, thanks for the info. I'll look into this

[Sebastien Piechurski]

Hello @Minh,

A number of users and vendors (including us Atos/Bull) are expecting to install the current 2.12 LTS on RHEL 7.7 with MOFED (which only 4.7 brings compatibility with RHEL 7.7 kernels).

On top of this, Peter announced last week during the LAD, that 2.12.3 would be released with compatibility of MOFED 4.7.

So I think it is needed to have this in b2_12.

You will also need to cherry-pick those dependencies which are not present on b2_12:

27572b047:  LU-12355 lnet: Adjust checks for ib_device_ops

bbc2cf593: LU-12400 lnet: Infiniband sg_dma changes for linux 5.1

46298ffe0b436a8cf1c60aa3d7bde7ae52c78d00: LU-12355 lnet: ib_fmr_pool_unmap returns void

@Minh, a zero cost support and just bug fixes for configure checks in patch.

I don't think we need this for b2_12
ashehata, please advise?
