/*
* DRM_UNLOCKED is implicit for all non-legacy DRM driver IOCTLs since Linux
* v4.10 commit fa5386459f06 "drm: Used DRM_LEGACY for all legacy functions"
* (Linux v4.4 commit ea487835e887 "drm: Enforce unlocked ioctl operation
* for kms driver ioctls" previously did it only for drivers that set the
* DRM_MODESET flag), so this will race with SET_CLIENT_CAP. Linux v4.11
* commit dcf727ab5d17 "drm: setclientcap doesn't need the drm BKL" also
* removed locking from SET_CLIENT_CAP so there is no use attempting to lock
* manually. The latter commit acknowledges that this can expose userspace
* to inconsistent behavior when racing with itself, but accepts that risk.
