From c90e2a9cfd94bd02d92c53b97f04fd595001de7e Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 14 Feb 2019 18:42:44 +0100 Subject: [PATCH] block-backend: Make blk_inc/dec_in_flight public For some users of BlockBackends, just increasing the in_flight counter is easier than implementing separate handlers in BlockDevOps. Make the helper functions for this public.
