There are many duplicated codes to check if the given string is
correct subvolume name. Introduce test_issubvolname() for this
purpose for simplicity.

unify these to '%s' format.

btrfs_lookup_csums_range() uses ALIGN() to check if start
and end + 1 are aligned to root-sectorsize. It's better to
replace these with IS_ALIGNED() for simplicity.

Hi Qu,
(2014/07/25
The original FIEMAP patch did not define this bit, btrfs will make use of
it. The defined constant maintains the same value as originally proposed.
Currently, the 'filefrag' utility has no way to recognize and denote a
compressed extent. As implemented in btrfs right now, the compression step
This flag was not accepted when fiemap was proposed [2] due to lack of
in-kernel users. Btrfs has compression for a long time and we'd like to
see that an extent is compressed in the output of 'filefrag' utility
once it's taught about it.
For that purpose, a reserved field from fiemap_extent is
