310 * The format:

312 * maintainer-errorid: [function-name:] message

314 * where errorid is unique to the maintainer and function-name is
315 * optional, is recommended, so that anyone can easily find the bug
316 * with a simple grep for the short to type string
317 * maintainer-errorid. Don't bother with reusing errorids, there are
318 * lots of numbers out there.
319 *
320 * Example:
321 *
322 * reiserfs_panic(
323 * p_sb, "reiser-29: reiserfs_new_blocknrs: "
324 * "one of search_start or rn(%d) is equal to MAX_B_NUM,"

329 *
330 * Regular panic()s sometimes clear the screen before the message can
331 * be read, thus the need for the while loop.
332 *
333 * Numbering scheme for panic used by Vladimir and Anatoly( Hans completely
334 * ignores this scheme, and considers it pointless complexity):
335 *
336 * panics in reiserfs_fs.h have numbers from 1000 to 1999
337 * super.c 2000 to 2999
338 * preserve.c (unused) 3000 to 3999
339 * bitmap.c 4000 to 4999
340 * stree.c 5000 to 5999
341 * prints.c 6000 to 6999
342 * namei.c 7000 to 7999
343 * fix_nodes.c 8000 to 8999
344 * dir.c 9000 to 9999
345 * lbalance.c 10000 to 10999
346 * ibalance.c 11000 to 11999 not ready
347 * do_balan.c 12000 to 12999
348 * inode.c 13000 to 13999
