Subject: radeon: ensure that timing/profiling queries are suspended on flush
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8a125afa6e88a3eeddba8c7fdc1a75c9b99d5489;p=mesa.git

radeon: ensure that timing/profiling queries are suspended on flush

The queries_suspended_for_flush flag is redundant because suspended queries
are not removed from their respective linked list.
