Btrfs: add statx support
Return enhanced file attributes from the btrfs, including:
(1). inode creation time as stx_btime, and
(2). Certain BTRFS_INODE_xxx flags are mapped to stx_attributes flags.
Example output:
[root@localhost ~]# cat t.sh
touch t
chattr +aic t
~/linux/samples/statx/test-statx t
chattr -aic t
touch t
