Hi Maxime,
Clang build fails will be fixed in v9. For checkpatch warning, it was due to pragma string inside.
Previous version can avoid such warning, while format is a little messy as below.
I prefer to keep code clean and more readable. How about your idea?
+#ifdef UNROLL_PRAGMA_PARAM
+#define VHOST_UNROLL_PRAGMA(param) _Pragma(param)
+#else
+#define VHOST_UNROLL_PRAGMA(param) do {} while (0);
+#endif
+ VHOST_UNROLL_PRAGMA(UNROLL_PRAGMA_PARAM)
+ for (i = 0; i < PACKED_BATCH_SIZE; i++)
Regards,
Marvin
