ext4: Add statx support
Return enhanced file attributes from the Ext4 filesystem. This includes
the following:
(1) The inode creation time (i_crtime) as stx_btime, setting STATX_BTIME.
(2) Certain FS_xxx_FL flags are mapped to stx_attribute flags.
This requires that all ext4 inodes have a getattr call, not just some of
them, so to this end, split the ext4_getattr() function and only call part
of it where appropriate.
Example output:
[root@andromeda ~]# touch foo
[root@andromeda ~]# chattr +ai foo
[root@andromeda ~]# /tmp/test-statx foo
statx(foo) = 0
