[Xen-devel] [PATCH v4 0/3] make sure PGC_extra pages are dealt with properly

Posted by Paul Durrant 3 weeks ago
This series was formerly called "remove one more shared xenheap page:
shared_info" but I have dropped the patches actually changing shared_info
and just left the PGC_extra clean-up that was previously intertwined.

Paul Durrant (3):
  mm: keep PGC_extra pages on a separate list
  x86 / ioreq: use a MEMF_no_refcount allocation for server pages...
  mm: add 'is_special_page' inline function...

So I'm confused - I had just replied twice to v6 patch 5/5. This
series calls itself v4 and consists of the middle three patches
of what v6 was. What's the deal? Is this really v7, and the two
patches have been dropped / postponed?

Sorry, I clearly got confused with numbering against one of my other series. Yes, this should be v7.

I wanted to send the patches that clear up use of PGC_extra, separating from the change to shared_info since I'm pressed for time to complete all the other conversions from xenheap pages such that I can send them as a single series.
