1ba4a712dd Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.
This bring huge amount of changes, I'll enumerate only user-visible changes:

- Delegated Administration

	Allows regular users to perform ZFS operations, like file system
	creation, snapshot creation, etc.

- L2ARC

	Level 2 cache for ZFS - allows to use additional disks for cache.
	Huge performance improvements mostly for random read of mostly
	static content.

- slog

	Allow to use additional disks for ZFS Intent Log to speed up
	operations like fsync(2).

- vfs.zfs.super_owner

	Allows regular users to perform privileged operations on files stored
	on ZFS file systems owned by him. Very careful with this one.

- chflags(2)

	Not all the flags are supported. This still needs work.

- ZFSBoot

	Support to boot off of ZFS pool. Not finished, AFAIK.

	Submitted by:	dfr

- Snapshot properties

- New failure modes

	Before if write requested failed, system paniced. Now one
	can select from one of three failure modes:
	- panic - panic on write error
	- wait - wait for disk to reappear
	- continue - serve read requests if possible, block write requests

- Refquota, refreservation properties

	Just quota and reservation properties, but don't count space consumed
	by children file systems, clones and snapshots.

- Sparse volumes

	ZVOLs that don't reserve space in the pool.

- External attributes

	Compatible with extattr(2).

- NFSv4-ACLs

	Not sure about the status, might not be complete yet.

	Submitted by:	trasz

- Creation-time properties

- Regression tests for zpool(8) command.

e327f52446 The sources covered by Sun's CDDL have been repo copied below the
src/cddl and src/sys/cddl directories per the core@ decision following
the license review.

This change modifies the affected Makefiles to reference the sources
in their new location.

ee8a5fa77d Remove _SOLARIS_C_SOURCE now that it doesn't do anything in FreeBSD
headers. All OpenSolaris compatibility comes via the set of specific
compatibility headers in src/compat/opensolaris and
src/sys/compat/opensolaris.

3b7917d766 - Reduce number of atomic operations needed to be implemented in asm by
implementing some of them using existing ones.
- Allow to compile ZFS on all archs and use atomic operations surrounded
  by global mutex on archs we don't have or can't have all atomic
  operations needed by ZFS.

d4c4dfe96f FreeBSD's namecache works quite well with ZFS, so remove DNLC. 2007-05-23 21:33:02 +00:00

8b384c52c0 MFp4: Now that ZFS can use FreeBSD's namecache, turn it off by default and
turn off DNLC, but don't remove DNLC yet just in case.
