2.4.5-ac5 locks on ReiserFS umount (ac4 doesn't)

[Pavel Roskin]

Hello!

I'm using ReiserFS in the kernel, not as a module. My root filesystem is
ReiserFS. I mounted another ReiserFS partition and then tried to unmount
it. umount hung. sync hung. shutdown hung.

Both umount and sync were shown in the "D" state on Ctrl-ScrollLock.

I reverted to 2.4.5-ac4 and could not reproduce the problem. I saw a
suggestion that it may have to do with module unloading, but in my case
reiserfs is not a module.
