VOP_RECLAIM accessing v_mount on mounted file systems is fine. On umounted
ones, no.

Assuming all of the timer cleanup is internal (not waiting for callbacks
or such that we have to answer to keep others going too), then Frank's
suggestion of moving the cleanup to VOP_INACTIVATE is fine.

Other solutions are to:

1) when unmounting, vgone all the vnodes on the file system

or

2) when unmounting, flag all the vnodes on the mountpint as "NFS DEAD" -
set an internal flag. Everything from then on ignores the mount info, and
waits for the eventual RECLAIM.

Take care,
