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 results=fff Size: 0 Blocks: 0 IO Block: 4096 regular file Device: 08:12 Inode: 2101950 Links: 1 Access: (0644/-rw-r--r--) Uid: 0 Gid: 0 Access: 2016-02-11 17:08:29.031795451+0000 Modify: 2016-02-11 17:08:29.031795451+0000 Change: 2016-02-11 17:11:11.987790114+0000 Birth: 2016-02-11 17:08:29.031795451+0000 Attributes: 0000000000000030 (-------- -------- -------- -------- -------- -------- -------- --ai----) Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
