avg f080f1459e MFV r323795: 8604 Avoid unnecessary work search in VFS when unmounting snapshots 
illumos/illumos-gate@ed992b0aac
ed992b0aac

https://www.illumos.org/issues/8604
  Every time we want to unmount a snapshot (happens during snapshot deletion or
  renaming) we unnecessarily iterate through all the mountpoints in the VFS layer
  (see zfs_get_vfs).
  Ideally we would just put a hold on the snapshot and access its respective VFS
  resource directly.

FreeBSD note: I added a FreeBSD specific function getzfsvfs_ref() which
is like getzfsvfs() but returns a filesystem referenced, not busied.
We want a busied filesystem in most cases, because we access its private
data and, thus, we need to prevent the filesystem from being unmounted
and its private data destroyed.  But in some cases we can either get
away with just a referenced filesystem or we must not busy the
filesystem.  Unmounting the filesystem is one of such cases.

README.md

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.
