[CC Theo & linux-ext4]

It's returning '0' in stx_btime for STATX_ALL or STATX_BTIME.

Looking at changes, I suspect:
  commit 927353987d503b24e1813245563cde0c6167af6e
  Author: Theodore Ts'o <tytso@xxxxxxx>

    ext4: avoid fetching btime in ext4_getattr() unless requested

and that perhaps it should be instead...

diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c

        struct ext4_inode_info *ei = EXT4_I(inode);

-       if ((query_flags & STATX_BTIME) &&
+       if ((request_mask & STATX_BTIME) &&
            EXT4_FITS_IN_INODE(raw_inode, ei, i_crtime)) {
                stat->result_mask |= STATX_BTIME;
                stat->btime.tv_sec = ei->i_crtime.tv_sec;

That allows test to pass again.
