I think I found a bug in ext4/extents.c, "ext4_ext_put_in_cache" uses
"__u32" to receive physical block number.  "ext4_ext_put_in_cache" is
used in "ext4_ext_get_blocks", it sets ext4 inode's extent cache
according most recently tree lookup (higher 16 bits of saved physical
block number are always zero). when serving a mapping request,
"ext4_ext_get_blocks" first check whether the logical block is in
inode's extent cache. if the logical block is in the cache and the
cached region isn't a gap, "ext4_ext_get_blocks" gets physical block
number by using cached region's physical block number and offset in
the cached region.  as described above, "ext4_ext_get_blocks" may
return wrong result when there are physical block numbers bigger than
0xffffffff.

You are right.  Thanks for reporting this!
