--- Comment #3 from Konstantin Belousov <[email protected]> ---
No, si_refcount is not a reference existing during the mapping lifetime.
The si_refcount is the transient refcount taken while a kernel thread operates
on the cdev.  For instance, in case of d_mmap, it is taken by dev_refthread()
in old_dev_pager_fault() around the call to csw->d_mmap, and released by the
nearby call(s) to dev_relthread().
