[PATCH v2 15/22] qemu: Don't pass redundant job name around

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of passing current job name to several functions which already
know what the current job is we can generate the name where we actually
need to use it.
