What we should instead do soon is support Linux preadv2 and the

This makes vfs_acl_common.c a subsystem of its own that acl_xattr and acl_tdb

This patch is a bit on the large and clumsy side, but splitting it up would

Add SMB_VFS_OFFLOAD_READ_SEND an SMB_VFS_OFFLOAD_READ_RECV.
This paves the way for supporting server-side copy-chunk with source and
destination file-handles on different shares. It can be used to
implement copy offload fsctl in the future, but for now this will be
used as a mere copy-chunk replacement.
SMB_VFS_OFFLOAD_READ generates a token that associates an fsp with the
token and stores the fsp in a in-memory db.
Initially only a copy-chunk resume key fsctl is supported. In the future
this can be enhanced to support real offload fsctl.

This module marks all file in the share as offline.
It can be useful for shares mounted on top of a remote file
system (either through a samba VFS module or via FUSE).
Offline files change the behavior of Windows explorer, and
prevent it from peeking inside folders just for the sake of
drawing a nice icon of them. This greatly reduces the number
of requests Windows Explorer makes, and improves user experience
when dealing with remote file systems.
The offline bit also has an effect on the behavior of Windows
redirector.

The shell_snap VFS module plumbs into the snapshot (aka shadow-copy)
management paths used by Samba's File Server Remote VSS Protocol (FSRVP)
server.
The following shell callouts may be configured in smb.conf:
shell_snap: check path command
- Called when an FSRVP client wishes to check whether a given
share supports snapshot create/delete requests.
- The command is called with a single <share path> argument.
- The command must return 0 if <share path> is capable of being
snapshotted.
shell_snap: create command
- Called when an FSRVP client wishes to create a snapshot.
- The command is called with a single <share path> argument.
- The command must return 0 status if the snapshot was
successfully taken.
- The command must output the path of the newly created snapshot
to stdout.
shell_snap: delete command
- Called when an FSRVP client wishes to delete a snapshot.
- The command is called with <base share path> and
<snapshot share path> arguments.
- The command must return 0 status if the snapshot was
successfully removed.

Based on <https://code.google.com/p/vfs-unityed-media/>.
The existing VFS module media_harmony has some problems relative to Avid
media sharing:
Avid looks at the modification time of the ingest directory. Since
media_harmony has everyone using the same directory, users (or client
systems) have to somehow create "fake" directories with special names
and then media_harmony returns the mod time of those fake directories
for the different clients rather than the actual mod time of the
communal ingest directory.
To make matters worse, users then have to have a special utility or
understand how to update the modtime on these specially named
directories. Otherwise, their client system will never update the
indexes to show new media.
To make it even worse than that, Avid creates new directories on the
fly, so you can't just set this up statically at the beginning. Avid
will silently create a new directory and your reindexing problems will
start all over until you create new fake directories.
With unityed_media:
* there are no reindexes between clients
* clients don't need to know which directories have been created for
them, it's automatic.
* clients never have to reindex other systems directories.
* unityed_media let's each client have their own directories.
* unityed_media works much more like Avid's own ISIS servers work.
A module option controls which name is appended to client specific
paths: the username, the hostname (will not work with OS X) or the
client's IP.

This module provides enhanced compatibility with Apple SMB clients and
interoperability with a Netatalk 3 AFP fileserver.
The module intercepts the OS X special streams "AFP_AfpInfo" and
"AFP_Resource" and handles them in a special way. All other named
streams are deferred to vfs_streams_xattr.
The OS X client maps all NTFS illegal characters to the Unicode
private range. This module optionally stores the charcters using their
native ASCII encoding.
Open modes are optionally checked against Netatalk AFP share modes.
The "AFP_AfpInfo" named stream is a binary blob containing OS X
extended metadata for files and directories. This module optionally
reads and stores this metadata in a way compatible with Netatalk 3
which stores the metadata in an EA "org.netatalk.metadata". Cf
source3/include/MacExtensions.h for a description of the binary blobs
content.
The "AFP_Resource" named stream may be arbitrarily large, thus it
can't be stored in an EA on most filesystem. ZFS on Solaris is an
exception to the rule, because it there EAs can be of any size and EAs
are first-class filesystem objects that can be used with normal file
syscalls like open(), read(), write(), fcntl() asf. This module stores
the AFP_Resource stream in an AppleDouble file, prepending "._" to the
filename. On Solaris and ZFS the stream is optionally stored in an EA
"org.netatalk.ResourceFork".
