  ZoL issues:
  Improved dnode allocation #6564
  Clean up large dnode code #6262
  Fix dnode_hold() freeing dnode behavior #8172
  Fix dnode allocation race #6414, #6439
  Partial: Raw sends must be able to decrease nlevels #6821, #6864
  Remove unnecessary txg syncs from receive_object() Closes #7197

This updates FreeBSD large_dnode code (that was imported from ZoL) to a
version that was committed to illumos.  It has some cleanups,
improvements and fixes comparing to what we have in FreeBSD now.
I think that the most significant update is 8199 multi-threaded
dmu_object_alloc().

This commit reverts r351077 that was a revert of r351074 and r351076 and
restores those changes.  Required atomic operations should be available
now on all platforms where we build ZFS.

FreeBSD Source:

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

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
