When I try to write cases about mount shared subtrees test, I find I

To make the code clear, I use a stack to save mounted points
sequentially, then I write 3 common functions to operate this stack.
1. The global stack named MOUNTED_POINT_STACK
2. _get_mount() accepts mount parameters like _mount() does, but the
mountpoint parameter must be the last one. It will run the
mount operation and push the mountpoint name into stack.
3. _put_mount() doesn't need any parameter. It will pop the newest
mountpoint name from the stack, and umount it.
4. _clear_mount_stack() doesn't need any parameter either. It will
umount all mountpoints in the stack sequentially, and set
MOUNTED_POINT_STACK=""
Generally, the _clear_mount_stack() function also can be used as
_init_mount_stack() at the beginning of a case. Because it will
prepare an empty stack.

generic: racing getxattr requests against xattr add/remove
This test reproduces a bug in XFS where a getxattr of an existing
xattr returns failure due to a race with a setxattr that causes
inode attribute fork conversion.

generic/158,304: filter dedupe error message
Kernel commit 22725ce4e4a0 ("vfs: fix isize/pos/len checks for reflink &
dedupe") added more checks on reflink and dedupe, rejected dedupe past
EOF early and explicitly, and causes generic/158 and generic/304 to fail.
Try dedupe from past EOF
-dedupe: Invalid argument
+XFS_IOC_FILE_EXTENT_SAME: Invalid argument
Try dedupe to past EOF, destination offset beyond EOF
Also there's an xfsprogs patch from Darrick ("xfs_io: prefix dedupe
command error messages consistently") to change all xfs_io dedupe
error message prefixes to "XFS_IOC_FILE_EXTENT_SAME".
So introduce a new _filter_dedupe_error, change all "dedupe" prefix
to XFS_IOC_FILE_EXTENT_SAME, make tests pass with both old/new
kernel & userspace.

Verify correct d_type values of dir entries.
This test does NOT require that file system support the filetype
