You people working hard to fix bugs and implement great filesystems
almost makes me feel bad for trying to break your code :)

^^^

Here I get (on x86 gcc 4.3.1):

fs/ext3/ialloc.c: In function 'ext3_orphan_get':
fs/ext3/ialloc.c:701: warning: format '%lu' expects type 'long unsigned int', but argument 2 has type 'unsigned int'

So it probably should be %u or something.
