printk ("bad key %lu %lu %lu %lu", key->k_dir_id, key->k_objectid,

/* 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
