linux-next: build warning after merge of the btrfs-kdave tree

[Stephen Rothwell]

Hi David,

After merging the btrfs-kdave tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/btrfs/inode.c: In function 'run_delalloc_range':
fs/btrfs/inode.c:1219:9: warning: 'cur_end' may be used uninitialized in this function [-Wmaybe-uninitialized]
   start = cur_end + 1;
         ^
fs/btrfs/inode.c:1172:6: note: 'cur_end' was declared here
  u64 cur_end;
      ^

Introduced by commit

  cow_file_range_async ("btrfs: Introduce COMPRESS reserve type to fix false enospc for compression")

Presumably a false positive because ASSERT(0) panics?
