Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ 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,"

+ 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

+ do_balan.c 12000 to 12999
