Susant Palai 48623a33a0 experimental/cloudsync: Download xlator for archival feature
spec-files:
https://review.gluster.org/#/c/18854/

Overview:
* Cloudsync maintains three file states in it's inode-ctx i.e
  1 - LOCAL,
  2 - REMOTE,
  3 - DOWNLOADING.

* A data modifying fop is allowed only if the state is LOCAL.
  If the state is REMOTE or DOWNLOADING, client will download
  or wait for the download to finish initiated by other client.

* Multiple download and upload from different clients are synchronized
  by inodelk.

* In POSIX a state check is done (part of different commit)before
  allowing the fop to continue. If the state is remote/downloading the
  fop is unwound with EREMOTE. The client will then download the file
  and continue with the fop again.

* Basic Algo for fop (let's say write fop):
  - If LOCAL -> resume fop
  - If REMOTE ->
	- INODELK
	- STAT (this gets state and heal the state if needed)
	- DOWNLOAD
	- resume fop

Note:
* Developers will need to write plugins for download, based on the
remote store they choose. In phase-1, support will be added for
one remote store per volume. In future, more options for multiple
remote stores will be explored.

TODOs:
 - Implement stat/lookup/readdirp to return size info from xattr
 - Make plugins configurable
 - Implement unlink fop
 - Add metrics collection
 - Add sharding support

GlusterFS Maintainers
=====================
The intention of this file is not to establish who owns what portions of the
code base, but to provide a set of names that developers can consult when they
have a question about a particular subset and also to provide a set of names
to be CC'd when submitting a patch to obtain appropriate review.
In general, if you have a question about inclusion of a patch, you should
consult gluster-devel@gluster.org and not any specific individual privately.
Descriptions of section entries:
M: Main contact that knows and takes care of this area
L: Mailing list that is relevant to this area
W: Web-page with status/info
Q: Patchwork web based patch tracking system site
T: SCM tree type and location. Type is one of: git, hg, quilt, stgit.
S: Status, one of the following:
Supported: Someone is actually paid to look after this.
Maintained: Someone actually looks after it.
Odd Fixes: It has a maintainer but they don't have time to do
much other than throw the odd patch in. See below.
Orphan: No current maintainer [but maybe you could take the
role as you write your new code].
Obsolete: Old code. Something tagged obsolete generally means
it has been replaced by a better system and you
should be using that.
F: Files and directories with wildcard patterns.
A trailing slash includes all files and subdirectory files.
F: drivers/net/ all files in and below drivers/net
F: drivers/net/* all files in drivers/net, but not below
F: */net/* all files in "any top level directory"/net
One pattern per line. Multiple F: lines acceptable.
X: Files and directories that are NOT maintained, same rules as F:
Files exclusions are tested before file matches.
Can be useful for excluding a specific subdirectory, for instance:
F: net/
X: net/ipv6/
matches all files in and below net excluding net/ipv6/
K: Keyword perl extended regex pattern to match content in a
patch or file. For instance:
K: of_get_profile
matches patches or files that contain "of_get_profile"
K: \b(printk|pr_(info|err))\b
matches patches or files that contain one or more of the words
printk, pr_info or pr_err
One regex pattern per line. Multiple K: lines acceptable.
P: Peer for a component
