- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
Snapshots may not be opened for writing and the attributes are read-only.
Use the mtime as the time this snapshot was taken.
Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
a vnode.
- Add snapshot support to ls, fsck_ffs and dump.
Welcome to 2.0F.

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h
* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.
These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).
suggested by uwe@, inspired by FreeBSD. The three flags override
each other (and the '-q' flag) and behave as follows:
-B Force printing of non-printable characters in file names as
\xxx, where xxx is the numeric value of the character in octal.
-b As -B, but use C escape codes whenever possible.
-w Force raw printing of non-printable characters. This is the
default when output is not to a terminal.
as requested by several users.
POSIX-2001 is unclear on conflicting option letters as far as the -g
option is concerned; a clarification request will be made.

too. The code in display() could possibly be a bit smarter about this
requirement...
Fixes the problem in PR bin/18321 from David Laight and PR bin/18436
from FUKAUMI Naoki.
round has been tested on Solaris/x86 and Linux hosts.
* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.
- fix bug where the 'clear' flag was set outside of main loop, so
"dump,uchg,arch" on a file with flags would clear all the bits
(because "dump" sets 'clear'). noted in FreeBSD PR 10071, and fix
obtained from FreeBSD.
- enforce right-most priority on arguments by clearing the appropriate
bit in the opposite set; if a string of "nouchg,uchg" is given,
chflags(8) would clear uchg because it applies the "set" bits before
clearing the "clear" bits. now, "uchg" sets UF_IMMUTABLE in setp
and also resets it in clrp, solving this problem
- constify second arg (the `default' arg)
