That is responding to Andrew, to indicate V2 patch has dependency on
arch_munmap in PPC. And I will review/test the code, I will respond to
Andrew directly.

PS Your statement above is entirely false, and out of context.

" You only told us that splitting a sealed vma is wrong (after I asked
you directly to answer) and then you made a comment about testing of
the patch set. Besides the direct responses to me, your comment was
"wait for me to test".

If you will excuse me, I would rather spend time on code/test and
other duties than responding to your false accusation.

Best regards,
