- optional, is recommended, so that anyone can easily find the bug
- with a simple grep for the short to type string
- 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,"
- "which means that we are optimizing location based on the bogus location of a temp buffer (%p).",

- Regular panic()s sometimes clear the screen before the message can
- be read, thus the need for the while loop.
- 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
- preserve.c (unused) 3000 to 3999
- bitmap.c 4000 to 4999
- stree.c 5000 to 5999
- prints.c 6000 to 6999
- namei.c 7000 to 7999
- fix_nodes.c 8000 to 8999
- dir.c 9000 to 9999
- lbalance.c 10000 to 10999
- ibalance.c 11000 to 11999 not ready
- do_balan.c 12000 to 12999
- inode.c 13000 to 13999
