[Qemu-devel] [PATCH v2 0/9] IDE: replace printfs with tracing

[John Snow <jsnow@redhat.com>]

Wherever possible, replace all printfs with proper tracing.
In most places I've tried to do a straight replacement, but
forthcoming patches may calibrate the tracing to be a little nicer.

For now, it's nice to just remove the all-or-nothing tracing.

For V2, I opted to leave in the nearly redundant tracers for now
with their individual names so that they can be targeted individually.

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
