The patch was sent last Wednesday and I hoped it could catch the 
merge window to be in v4.14 so we won't have to request a backport
for the v4.14 stable kernel in future. And I was not exactly sure when
the merge window was. Sorry :-)

The patch is not fixing a serious regression. It just fixes a long standing
issue from the beginning of the Hyper-V vPCI driver: 1 of 7 Mellanox 
VFs of a 32-vCPU VM running on Hyper-V may not receive interrupts.

Thanks,

The patch was sent last Wednesday and I hoped it could catch the=20
merge window to be in v4.14 so we won't have to request a backport
for the v4.14 stable kernel in future. And I was not exactly sure when
the merge window was. Sorry :-)

The patch is not fixing a serious regression. It just fixes a long standing
issue from the beginning of the Hyper-V vPCI driver: 1 of 7 Mellanox=20
VFs of a 32-vCPU VM running on Hyper-V may not receive interrupts.
