Description

It looks like there are a couple of definitions that differ between wirecheck and wiretest.

This is in wiretest, but not wirecheck:

+       LASSERTF((int)offsetof(struct llog_log_hdr, llh_reserved) == 84, "found %lld\n",
+                (long long)(int)offsetof(struct llog_log_hdr, llh_reserved));
+       LASSERTF((int)sizeof(((struct llog_log_hdr *)0)->llh_reserved) == 4, "found %lld\n",
+                (long long)(int)sizeof(((struct llog_log_hdr *)0)->llh_reserved));
+       LASSERTF((int)offsetof(struct llog_log_hdr, llh_bitmap) == 88, "found %lld\n",
+                (long long)(int)offsetof(struct llog_log_hdr, llh_bitmap));
+       LASSERTF((int)sizeof(((struct llog_log_hdr *)0)->llh_bitmap) == 8096, "found %lld\n",
+                (long long)(int)sizeof(((struct llog_log_hdr *)0)->llh_bitmap));
+       LASSERTF((int)offsetof(struct llog_log_hdr, llh_tail) == 8184, "found %lld\n",
+                (long long)(int)offsetof(struct llog_log_hdr, llh_tail));
+       LASSERTF((int)sizeof(((struct llog_log_hdr *)0)->llh_tail) == 8, "found %lld\n",
+                (long long)(int)sizeof(((struct llog_log_hdr *)0)->llh_tail));

The other difference is with fiemap_extent where wirecheck has fe_device, but wiretest still references fe_reserved.

-       LASSERTF((int)offsetof(struct fiemap_extent, fe_reserved[0]) == 44, "found %lld\n",
-                (long long)(int)offsetof(struct fiemap_extent, fe_reserved[0]));
-       LASSERTF((int)sizeof(((struct fiemap_extent *)0)->fe_reserved[0]) == 4, "found %lld\n",
-                (long long)(int)sizeof(((struct fiemap_extent *)0)->fe_reserved[0]));
+       LASSERTF((int)offsetof(struct fiemap_extent, fe_device) == 44, "found %lld\n",
+                (long long)(int)offsetof(struct fiemap_extent, fe_device));
+       LASSERTF((int)sizeof(((struct fiemap_extent *)0)->fe_device) == 4, "found %lld\n",
+                (long long)(int)sizeof(((struct fiemap_extent *)0)->fe_device));
