Subject: block: use 'unsigned' for in_flight field on driver state
X-Git-Tag: v7.1.0-rc0~46^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1b8f777673985af366de099ad4e41d334b36fb12;p=thirdparty%2Fqemu.git

block: use 'unsigned' for in_flight field on driver state

This patch makes in_flight field 'unsigned' for BDRVNBDState and
MirrorBlockJob. This matches the definition of this field on BDS
and is generically correct - we should never get negative value here.
