* The format:
*
* maintainer-errorid: [function-name:] message
*
* where errorid is unique to the maintainer and function-name is
* 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).",
* rn, bh
* );
*
* 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
* file.c 14000 to 14999
* objectid.c 15000 - 15999
