Hi Michal

Acked-by: James Zhu <James.Zhu@xxxxxxx> for the series
Best Regards!

Are there any objections to this series? We have been running into
this limit as a problem for a while now on big servers.
I don't think there were any objections, just a general lack of
interest - so there are no R-b / Acks.
If you're interested to have a go at it - I can resend it.
It should still apply on latest drm-tip.

64 DRM device nodes is not enough for everyone.
Upgrade it to ~512K (which definitely is more than enough).
To allow testing userspace support for >64 devices, add additional DRM
modparam (force_extended_minors) which causes DRM to skip allocating minors
in 0-192 range.
Additionally - convert minors to use XArray instead of IDR to simplify the
locking.
v1 -> v2:
Don't touch DRM_MINOR_CONTROL and its range (Simon Ser)
v2 -> v3:
Don't use legacy scheme for >=192 minor range (Dave Airlie)
Add modparam for testing (Dave Airlie)
Add lockdep annotation for IDR (Daniel Vetter)
v3 -> v4:
Convert from IDR to XArray (Matthew Wilcox)
v4 -> v5:
Fixup IDR to XArray conversion (Matthew Wilcox)
v5 -> v6:
Also convert Accel to XArray
Rename skip_legacy_minors to force_extended_minors
Michał Winiarski (4):
drm: Use XArray instead of IDR for minors
accel: Use XArray instead of IDR for minors
drm: Expand max DRM device number to full MINORBITS
drm: Introduce force_extended_minors modparam
