CVS commit: src/sys

Module Name:	src
Committed By:	simonb
Date:		Tue May 26 14:57:25 UTC 2026

Modified Files:
	src/sys/dev/dkwedge: dk.c
	src/sys/kern: kern_hook.c kern_subr.c
	src/sys/sys: systm.h

Log Message:
Add "rootspec" hooks.  These hooks add a generic mechanism for
devices to advertise extra root device choices.  Use these to
replace wedge-specific code in sys/kern/kern_subr.c .

XXX todo: rootspec configuraton can be unloaded after the root
filesystem is mounted, and rootspechook_establish() calls after
the root filesystem is mounted could then be a no-op.

Thanks riastradh@, mlelstv@ and chs@ for reviews and comments.
