[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 04/35] libxl.c: switch to LOG*D use
Use LOG*D functions to output the domain ID in logs as much as
possible. This will help consumer code sorting the logs by
domain.
This commit includes all LOG* to LOG*D changes where the domain
ID is not just a domid variable. We want the domain ID provided
to the LOG*D functions to be the one of the publicly known
domain, not a stubdom one.
