This makes it a "hot" header, so it should avoid pulling in unnecessary definitions. The header currently includes linux/error-injection.h to obtain the definition of `struct error_injection_entry`. However, this is unnecessary because the type is only referenced in the file as a pointer, for which an incomplete type is sufficient. Add explicit includes of linux/error-injection.h to files that use the ALLOW_ERROR_INJECTION() macro and currently rely on it being provided indirectly via linux/module.h. Then remove the linux/error-injection.h include from linux/module.h. The first five patches can go through their respective trees if preferred. The final patch depends on the preceding cleanups. --- Petr Pavlu (6): block: Include error-injection.h for ALLOW_ERROR_INJECTION() net: Include error-injection.h for ALLOW_ERROR_INJECTION() syscalls: Include error-injection.h for ALLOW_ERROR_INJECTION() drm/i915: Include error-injection.h for ALLOW_ERROR_INJECTION() drm/xe: Include error-injection.h for ALLOW_ERROR_INJECTION() module: Remove the error-injection.h include from linux/module.h block/blk-core.c | 1 + drivers/gpu/drm/i915/display/intel_connector.c | 1 + drivers/gpu/drm/i915/display/intel_display_driver.c | 1 + drivers/gpu/drm/i915/gt/intel_engine_cs.c | 1 + drivers/gpu/drm/i915/gt/intel_gt.c | 2 ++ drivers/gpu/drm/i915/gt/uc/intel_guc_ct.c | 1 + drivers/gpu/drm/i915/gt/uc/intel_uc.c | 1 + drivers/gpu/drm/i915/gt/uc/intel_uc_fw.c | 1 + drivers/gpu/drm/i915/i915_driver.c | 1 + drivers/gpu/drm/i915/i915_pci.c | 2 ++ drivers/gpu/drm/i915/intel_uncore.c | 1 + drivers/gpu/drm/xe/xe_device.c | 2 +- drivers/gpu/drm/xe/xe_exec_queue.c | 1 + drivers/gpu/drm/xe/xe_ggtt.c | 2 +- drivers/gpu/drm/xe/xe_guc.c | 1 + drivers/gpu/drm/xe/xe_guc_ads.c | 2 +- drivers/gpu/drm/xe/xe_guc_ct.c | 2 +- drivers/gpu/drm/xe/xe_guc_log.c | 2 +- drivers/gpu/drm/xe/xe_guc_relay.c | 2 +- drivers/gpu/drm/xe/xe_hw_engine_class_sysfs.c | 1 + drivers/gpu/drm/xe/xe_hw_engine_group.c | 2 ++ drivers/gpu/drm/xe/xe_mmio.c | 1 + drivers/gpu/drm/xe/xe_oa.c | 1 + drivers/gpu/drm/xe/xe_pm.c | 2 +- drivers/gpu/drm/xe/xe_pt.c | 2 ++ drivers/gpu/drm/xe/xe_pxp.c | 2 ++ drivers/gpu/drm/xe/xe_sriov.c | 2 +- drivers/gpu/drm/xe/xe_sync.c | 1 + drivers/gpu/drm/xe/xe_tile.c | 2 +- drivers/gpu/drm/xe/xe_tuning.c | 2 ++ drivers/gpu/drm/xe/xe_uc_fw.c | 2 +- drivers/gpu/drm/xe/xe_vm.c | 1 + drivers/gpu/drm/xe/xe_wa.c | 2 +- drivers/gpu/drm/xe/xe_wopcm.c | 2 +- drivers/net/netdevsim/tc.c | 1 + include/linux/compat.h | 1 + include/linux/module.h | 1 - include/linux/syscalls.h | 1 + kernel/module/main.c | 1 + net/core/skb_fault_injection.c | 1 + 40 files changed, 45 insertions(+), 13 deletions(-) --- base-commit: df2908090cda368b01ff43709f51890076c56157 change-id: 20260816-module-include-error_injection-4f80e37a8ea6
