321 "one of search_start or rn(%d) is equal to MAX_B_NUM,"

328
329 Numbering scheme for panic used by Vladimir and Anatoly( Hans completely ignores this scheme, and considers it
330 pointless complexity):
331
332 panics in reiserfs_fs.h have numbers from 1000 to 1999
333 super.c 2000 to 2999
334 preserve.c (unused) 3000 to 3999
335 bitmap.c 4000 to 4999
336 stree.c 5000 to 5999
337 prints.c 6000 to 6999
338 namei.c 7000 to 7999
339 fix_nodes.c 8000 to 8999
340 dir.c 9000 to 9999
341 lbalance.c 10000 to 10999
