Hi
I am still using HPFS. I have some data on it that I share with OS/2.

This was a problem back in the kernels 2.6.*. I fixed it long time ago
(see the commit 7dd29d8d865efdb00c0542a5d2c87af8c52ea6c7 and the merge
7f4238a0ef8858e1f9b02a874b5818f6e9846673).
I am using it with SMP and PREEMPT, it does nothing weird. It just locks
everything with a per-filesystem mutex.

This is a regular bug, not a security bug. You can't gain unauthorized
access throught this.
