Right, but does nesting even apply here? I mean, AFAICR the commit
message, we're talking about per-thread transaction disabling. IOW, this
is an on/off button used in a boolean context.
Or is this going to be used as a mechanism to tisable TSX when max
nesting level has been reached?
Hmmm.
Btw, the disable/reenable_txn() aren't used anywhere in the patchset and
I'd actually like to get an idea where/how those are used.
Thanks.
