Subject: [PATCH RFC V2 0/6] rxe_map_mr_sg() fix cleanup and refactor
I don't collect the Reviewed-by to the patch1-2 this time, since i
think we can make it better.
Patch1-2: Fix kernel panic[1] and benifit to make srp work again.
Almost nothing change from V1.
Patch3-5: cleanups # newly add
Patch6: make RXE support PAGE_SIZE aligned mr # newly add, but not fully tested
My bad arm64 mechine offten hangs when doing blktests even though i use the
default siw driver.
- nvme and ULPs(rtrs, iser) always registers 4K mr still don't supported yet.
