>Organization:
none
>Environment:
FreeBSD 3.0-CURRENT i386, elf kernel
>Description:
Count of user refs to KLD decremented before call to function
linker_file_unload, so if module refuses to unload once, it will be impossible
to unload it again, even if module ready to unload.
>How-To-Repeat:
Load any filesystem module, mount corresponding file system, try
to unload. Then umount previosly mounted file system and try to unload module
again.
