From b036d9ac690943af93929ede376c4482c8f97bf2 Mon Sep 17 00:00:00 2001 From: Christian Schoenebeck Date: Mon, 19 Oct 2020 13:10:18 +0200 Subject: [PATCH] 9pfs: suppress performance warnings on qtest runs Don't trigger any performance warning if we're just running test cases, because tests intentionally run for edge cases. So far performance warnings were suppressed for the 'synth' fs driver backend only. This patch suppresses them for all 9p fs driver backends.
