Today, I reverted the part of commit that tried to transform destroy_dev()
from d_close() into destroy_dev_sched(). See kern_conf.c, rev. 1.208.
You shall call destroy_dev_sched() explicitely.


Does this mean that mount_smbfs has to explicitly call it now? It is
currently stuck in the devdrn state with the latest kernel :(

Exactly. Patch by Tai-hwa Liang is pending. I also remember that sg(4)

  I'll ask for re@'s approval tomorrow.  Hopefully the new KPI would have
more exposure before my patch is committed.

had the same problem, but I do not know it current status.

  Though it was reviewed before destroy_dev_sched() KPI enters to the tree,
I'd be appreciate it if you can reviewed the attached patch again.
