Thanks, I'll read this over.
What's the motivation here? To shift over to ib_create_send_mad() so
that all the MAD-related DMA mapping stuff is in one place, to make it
easier to fix?
Yes - the motivation is to fix the DMA mapping issue that you pointed out by
changing ib_post_send_mad() to take an ib_mad_send_buf as input.
There are three places that I see where ib_post_send_mad() is called without
using ib_create_mad_send(): sa_query, mthca_mad, and agent. (Their
implementation pre-dates the call.) My intent was to patch each of these
separately to use ib_create_mad_send(), then apply a patch to convert the API.
If the API does not change to take an ib_mad_send_buf, then it's your call
whether to apply the patch.
