Is any of this in linux-next now?

Yep, Jan's patch caused the build breakage.
Because generic_find_next_le_bit() is not available for all
archtectures. So we should use ext2_find_next_bit() here.

Most architectures use the definitions in asm-generic, so they're OK.
M68k doesn't. S390 is also affected, and I think arm as well (but there's no
arm all-modconfig build in linux-next, so I'm not 100% sure).
I'm cooking a patch...

Subject: [PATCH] m68k: Implement generic_find_next_{zero_,}le_bit()
linux-next:
fs/udf/balloc.c: In function 'udf_bitmap_new_block':
fs/udf/balloc.c:274: error: implicit declaration of function
'generic_find_next_le_bit'
Convert ext2_find_next_{zero_,}bit() into generic_find_next_{zero_,}le_bit(),
and wrap the ext2_find_next_{zero_,}bit() around the latter.

I've now used Akinobu's patch so yours isn't really needed but it's a
good cleanup anyway in my opinion.
