In the log, at the very early stage line 894, aufs produces BUG msg.

It happened when mkdir[847] issues exit(2). At exitting, all opened
file descriptors are closed by kernel and aufs_release_dir() is
called.
By enabling CONFIG_AUFS_DEBUG, aufs checks the state of the internal
lock and found it is still locked which sould not happen. I don't
think
it sane. I am really doubtful "Is it really correctly built?"
Reading the source files of debian kernel 4.19.67-2+deb10u1, I've found
a suspicious thing.
- aufs4-mmap.patch is applied in-correctly,
or in-correct version is applied,
or bad aufs version which contained a in-correct version is used.
The last part of mm/nommu.c:do_mmap(),
fput(vma->vm_file);
should be
vma_fput(vma);
Changing that did not solve the problem.
