Merge branch 'net-smc-userspace-breakage-fixes'
Eugene Syromiatnikov says:
====================
net/smc: userspace breakage fixes
These two patches correct some userspace-affecting issues introduced
during 4.19 development cycle, specifically:
* New structure "struct smcd_diag_dmbinfo" has been defined in a way
that would lead to different layout of the structure on most 32-bit
ABIs in comparison with layout on 64-bit ABIs;
* One of the commits renamed an UAPI-exposed field name.
Changes since v1:
* Managed not to forget to add --cover-letter.
* Commit ID format in commit message has been changed in accordance
with Sergei Shtylyov's recommendations.
