Hi Jens,

I'll push a better version soon, it inverts the ifdef logic like this:

--- a/include/uapi/linux/io_uring.h
+++ b/include/uapi/linux/io_uring.h
@@ -10,7 +10,15 @@

  #include <linux/fs.h>
  #include <linux/types.h>
+/*
+ * this file is shared with liburing and that has to autodetect
+ * if linux/time_types.h is available or not, it can
+ * define UAPI_LINUX_IO_URING_H_SKIP_LINUX_TIME_TYPES_H
+ * if linux/time_types.h is not available
+ */
+#ifndef UAPI_LINUX_IO_URING_H_SKIP_LINUX_TIME_TYPES_H
  #include <linux/time_types.h>
+#endif

It also means that projects without liburing usage are not affected.
And developers only have to care if they want to build on legacy systems
without time_types.h

Once that's accepted into the kernel I'll adjust the logic in liburing

Does that sound like a plan?
