[PATCH v2 0/2] KVM: x86: read the PML log in the same order it was written

Posted by Maxim Levitsky 1 year, 1 month ago

Reverse the order in which
the PML log is read to align more closely to the hardware. It should
not affect regular users of the dirty logging but it fixes a unit test
specific assumption in the dirty_log_test dirty-ring mode.

Best regards,
       Maxim Levitsky
