Alan Somers 7ac72c256f vdev_geom may associate multiple vdevs per g_consumer
vdev_geom.c currently uses the g_consumer's private field to point to a
vdev_t. That way, a GEOM event can cause a change to a ZFS vdev. For
example, when you remove a disk, the vdev's status will change to REMOVED.
However, vdev_geom will sometimes attach multiple vdevs to the same GEOM
consumer. If this happens, then geom events will only be propagated to one
of the vdevs.

Fix this by storing a linked list of vdevs in g_consumer's private field.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c

* g_consumer.private now stores a linked list of vdev pointers associated
  with the consumer instead of just a single vdev pointer.

* Change vdev_geom_set_physpath's signature to more closely match
  vdev_geom_set_rotation_rate

* Don't bother calling g_access in vdev_geom_set_physpath. It's guaranteed
  that we've already accessed the consumer by the time we get here.

* Don't call vdev_geom_set_physpath in vdev_geom_attach. Instead, call it
  in vdev_geom_open, after we know that the open has succeeded.

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.

The buildkernel and installkernel targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.

Note: If you want to build and install the kernel with the buildkernel and installkernel targets, you might need to build world before. More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
