/* debugging reiserfs we used to print out a lot of different

most fields matter. So it took a long time just to write
appropriative printk. With this reiserfs_warning you can use format
specification for complex structures like you used to do with
printfs for integers, doubles and pointers. For instance, to print
out key structure you have to write just:
reiserfs_warning ("bad key %k", key);
instead of
printk ("bad key %lu %lu %lu %lu", key->k_dir_id, key->k_objectid,
key->k_offset, key->k_uniqueness);

/* 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
