WG Zoom notes

Folks,

RRSagent bot timed out today after the WG Zoom call, and left the IRC
channel before I managed to make minutes from our notes. I think our
minutes can still be recovered, but just in case - here are the raw notes
taken during our discussion. Many thanks to Skef for scribing today!

12:12 <skef> Topic: patch categorization changes
12:13 <skef> Wanted a better way to categorize patches beyond "dependent"
and "indpendent"
12:13 <skef> Dependent patches might need their own sets of "independent"
patches
12:14 <skef> Now have "full invalidation", "partial invalidation" and "no
invalidation" patches
12:14 <skef> Indicates what patches invalidate what other patches with
finer granularity
12:17 <skef> Question: should there still be two equivalent tables IFT/IFTX
or should they be more specific
12:22 *** Garret* (~Garret@7a930742.publics.cloak)* has quit *(Garret)*
12:25 <skef> We'll consider whether we might need 3 tables or whether we
can be more specific about what patch types go into what tables (and
reconsider naming)
