+Subject: block/blk-iocost (gcc13): keep large values in a new enum
+
+Since gcc13, each member of an enum has the same type as the enum [1]. And
+that is inherited from its members. Provided:
+  VTIME_PER_SEC_SHIFT     = 37,
+  VTIME_PER_SEC           = 1LLU << VTIME_PER_SEC_SHIFT,
+  ...
+  AUTOP_CYCLE_NSEC        = 10LLU * NSEC_PER_SEC,
+the named type is unsigned long.
+
+This generates warnings with gcc-13:
+  block/blk-iocost.c: In function 'ioc_weight_prfill':
+  block/blk-iocost.c:3037:37: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int'
+
+  block/blk-iocost.c: In function 'ioc_weight_show':
+  block/blk-iocost.c:3047:34: error: format '%u' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int'
+
+So split the anonymous enum with large values to a separate enum, so
+that they don't affect other members.
