Hi all, After merging the drm tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from drivers/gpu/drm/i915/i915_debugfs.c:39: drivers/gpu/drm/i915/gt/intel_gt_requests.h:9:10: fatal error: stddef.h: No such file or directory 9 | #include | ^~~~~~~~~~ Caused by commit 564f963eabd1 ("isystem: delete global -isystem compile option") from the kbuild tree interacting with commit b97060a99b01 ("drm/i915/guc: Update intel_gt_wait_for_idle to work with GuC") I have applied the following patch for today.
