Hi,
Bisecting points me to this commit:
commit 92fb58afaa2f38a9369ad5791a4cbf135545617d
Author: Baokun Li <libaokun1@xxxxxxxxxx>

common: xfstests support overlay+tmpfs
It breaks this command:
./check -n -overlay -g auto
As a result, it fails to show me the list of testcases.
Please help to check.
Thanks!

Thank you very much for reporting this issue!
I think I figured out the cause of the problem.
In the above commit, the "-t $OVL_BASE_FSTYP" command is used to
specify the overlay base mount file system type. If FSTYP is used to
specify BASE_FSTYP in config, the file system type can be identified.
However, if you use the environment variable FSTYP to specify BASE_FSTYP,
there is no corresponding logic. Sometimes, even FSTYP is not specified.
In this case, the mounting command is similar to
"_mount -t /dev/sdb /tmp/scratch".
As a result, the preceding problem is triggered.
I will send a patch to fix the problem.
Thanks!
