From acf2e2d96645b9299a0cf2d54fcb99169359f688 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Fri, 12 Nov 2021 09:54:39 +0000 Subject: [PATCH] docs: update cmdprio_percentage documentation Commit 1437d6357429 ("libaio,io_uring: relax cmdprio_percentage constraints") relaxed the cmdprio_percentage constraints such that cmdprio_percentage and prioclass/prio could be used together. However, it forgot to remove the mention of this constraint from the docs. Update the docs to reflect the new behavior.
