This seems to introduce a new warning:

  In file included from fs/btrfs/ctree.c:22:0:
  fs/btrfs/ctree.c: In function ‘btrfs_search_old_slot’:
  fs/btrfs/ctree.h:2117:240: warning: ‘old_generation’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
  fs/btrfs/ctree.c:1178:6: note: ‘old_generation’ was declared here

which looks like just gcc being unable to see that it is only used
when set, but it's still annoying. I'd suggest initializing it to 0
just to shut up the compiler. Ok?
