hi everyone,
this patchset reworks the drm.debug controlled debug categories,
and remaps them to use dynamic_debug_exec_queries().
To do this "smoothly", DRM_UT_* is converted from an enum to a
class-prefix string, which is prepended## to the real format string.
This lets us use:
$> echo module drm\* format ^drm:kms: +p > /proc/dynamic_debug/control
3rd patch fixes a conflict while rebasing to rc3. I kept the fixup
separate for more visibility.

drm/print: Fixup DRM_DEBUG_KMS_RATELIMITED()
Since we're about to move drm_dp_helper.c over to drm_dbg_*(), we'll want
to make sure that we can also add ratelimited versions of these macros in
order to retain some of the previous debugging output behavior we had.
I can see I havent been paying attention.
Are plans laid out where I can catch up quickly ?
Separately, but related, I have an RFC patchset on LKML to reduce
DYNAMIC_DEBUG's memory overhead. Patch 34 hints that rate-limiting
can be done dynamically, on demand, for any prdbg known to
dynamic_debug.
