Subject: i965/drm: Fold drm_bacon_gem_reset_stats into the callers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4cb3e4429d3868ffa2078e4cf772578418028ed1;p=mesa.git

i965/drm: Fold drm_bacon_gem_reset_stats into the callers.

We're going to get rid of drm_bacon_context shortly, so we'd have to
change the interface slightly.  It's basically just an ioctl wrapper
that isn't terribly bufmgr-related, so We may as well just combine it
with the code in brw_reset.c that actually uses it.
