[Qemu-devel] [PATCH v2 0/2] qemu-error: advanced report_once handling

[Cornelia Huck <cohuck@redhat.com>]

[Markus: I've decided to not include your R-b, as I did too many changes
to feel comfortable with that.]

[Also note that I'm about to disappear on vacation, so don't expect
quick responses. I just want to get it out before I forget about it.]

Based on previous discussions, I wanted to enhance the recently
merged report_once infrastucture with a way to print a message
once based on a variable instead of globally-once, similar to
what vfio-ccw uses today.

Not really tested, mainly wanted to get this out before my vacation
to get the ball rolling.

v1->v2:
- merged patch 3 (use the new function in vfio-ccw) into patch 1
- require a non-NULL 'printed' parameter
- have the functions return whether something was printed and slightly
  simplify the existing macros
- adapt macro formatting to suit my aesthetic sensibilities

Cornelia Huck (2):
  qemu-error: add {error,warn}_report_once_cond
  qemu-error: make use of {error,warn}_report_once_cond
