fsck_ffs opens the root filesystem on /dev/sd0a during boot. Before
it does so, sd0's sc->sc_dk.dk_copenmask member is 0. After fsck_ffs
has finished, dk_copenmask is 1. I can stop the kernel when it opens
/dev/sd0a with breakpoints at cdev_open, sdopen, VOP_OPEN, vn_open,
and spec_open. I cannot stop the kernel at a corresponding VOP_CLOSE,
vn_close, spec_close, cdev_close, or sdclose call during a fsck_ffs
system call. It is a mystery to me how fsck_ffs can open the device and
(seemingly) never close it, not even implicitly. Any ideas what's going
on?
dk_copenmask never returns to 0, not even during shutdown.
As a consequence of this dk_copenmask I am running 5.99.15. The problem
seems to be relatively new.
