+ * maintainer-errorid. Don't bother with reusing errorids, there are
+ * lots of numbers out there.
+ *
+ * Example:
+ *
+ * reiserfs_panic(
+ * p_sb, "reiser-29: reiserfs_new_blocknrs: "
+ * "one of search_start or rn(%d) is equal to MAX_B_NUM,"

+ *
+ * Numbering scheme for panic used by Vladimir and Anatoly( Hans completely
+ * ignores this scheme, and considers it pointless complexity):
+ *
+ * panics in reiserfs_fs.h have numbers from 1000 to 1999
+ * super.c 2000 to 2999
