Minor changes to the type of few varaibles was required
as comparison between "unsigned int" and "int"

The default snapshot name should be time stamp,
instead of that "snapshot" was getting assigned
as a snapshot name. This patch also fixes the
default snapshot name problem.

GL-31: Ability to restore snapshot
Implemented snapshot restore for thin logical volume. As of now snapshot
restore for CG is not tested. Testing for snapshot restore of a volume
is done by changing the snapshot create process to create a thick snapshot.
This is done because --merge option to restore thin volume is not working in
the latest kernel.

Current BD xlator (block backend) has a few limitations such as
* Creation of directories not supported
* Supports only single brick
* Does not use extended attributes (and client gfid) like posix xlator
* Creation of special files (symbolic links, device nodes etc) not
supported
Basic limitation of not allowing directory creation is blocking
oVirt/VDSM to consume BD xlator as part of Gluster domain since VDSM
creates multi-level directories when GlusterFS is used as storage
backend for storing VM images.
To overcome these limitations a new BD xlator with following
improvements is suggested.
* New hybrid BD xlator that handles both regular files and block device
files
* The volume will have both POSIX and BD bricks. Regular files are
created on POSIX bricks, block devices are created on the BD brick (VG)
* BD xlator leverages exiting POSIX xlator for most POSIX calls and
hence sits above the POSIX xlator
* Block device file is differentiated from regular file by an extended
attribute
* The xattr 'user.glusterfs.bd' (BD_XATTR) plays a role in mapping a
posix file to Logical Volume (LV).
* When a client sends a request to set BD_XATTR on a posix file, a new
LV is created and mapped to posix file. So every block device will
have a representative file in POSIX brick with 'user.glusterfs.bd'
(BD_XATTR) set.
* Here after all operations on this file results in LV related
operations.
For example opening a file that has BD_XATTR set results in opening
the LV block device, reading results in reading the corresponding LV
block device.
When BD xlator gets request to set BD_XATTR via setxattr call, it
creates a LV and information about this LV is placed in the xattr of the
posix file. xattr "user.glusterfs.bd" used to identify that posix file
is mapped to BD.
Usage:
Server side:
[root@host1 ~]# gluster volume create bdvol host1:/storage/vg1_info?vg1 host2:/storage/vg2_info?vg2
It creates a distributed gluster volume 'bdvol' with Volume Group vg1
using posix brick /storage/vg1_info in host1 and Volume Group vg2 using
/storage/vg2_info in host2.
[root@host1 ~]# gluster volume start bdvol
Client side:
[root@node ~]# mount -t glusterfs host1:/bdvol /media
[root@node ~]# touch /media/posix
It creates regular posix file 'posix' in either host1:/vg1 or host2:/vg2 brick
[root@node ~]# mkdir /media/image
[root@node ~]# touch /media/image/lv1
It also creates regular posix file 'lv1' in either host1:/vg1 or
host2:/vg2 brick
[root@node ~]# setfattr -n "user.glusterfs.bd" -v "lv" /media/image/lv1
[root@node ~]#
Above setxattr results in creating a new LV in corresponding brick's VG
and it sets 'user.glusterfs.bd' with value 'lv:<default-extent-size'
[root@node ~]# truncate -s5G /media/image/lv1
It results in resizig LV 'lv1'to 5G
New BD xlator code is placed in xlators/storage/bd directory.
Also add volume-uuid to the VG so that same VG can't be used for other
bricks/volumes. After deleting a gluster volume, one has to manually
remove the associated tag using vgchange <vg-name> --deltag
<trusted.glusterfs.volume-id:<volume-id>>
Changes from previous version V5:
* Removed support for delayed deleting of LVs
Changes from previous version V4:
* Consolidated the patches
* Removed usage of BD_XATTR_SIZE and consolidated it in BD_XATTR.
Changes from previous version V3:
* Added support in FUSE to support full/linked clone
* Added support to merge snapshots and provide information about origin
* bd_map xlator removed
* iatt structure used in inode_ctx. iatt is cached and updated during
fsync/flush
* aio support
* Type and capabilities of volume are exported through getxattr
Changes from version 2:
* Used inode_context for caching BD size and to check if loc/fd is BD or
not.
* Added GlusterFS server offloaded copy and snapshot through setfattr
FOP. As part of this libgfapi is modified.
* BD xlator supports stripe
* During unlinking if a LV file is already opened, its added to delete
list and bd_del_thread tries to delete from this list when a last
reference to that file is closed.
Changes from previous version:
* gfid is used as name of LV
* ? is used to specify VG name for creating BD volume in volume
create, add-brick. gluster volume create volname host:/path?vg
* open-behind issue is fixed
* A replicate brick can be added dynamically and LVs from source brick
are replicated to destination brick
* A distribute brick can be added dynamically and rebalance operation
distributes existing LVs/files to the new brick
* Thin provisioning support added.
* bd_map xlator support retained
* setfattr -n user.glusterfs.bd -v "lv" creates a regular LV and
setfattr -n user.glusterfs.bd -v "thin" creates thin LV
* Capability and backend information added to gluster volume info (and
--xml) so
that management tools can exploit BD xlator.
* tracing support for bd xlator added
TODO:
* Add support to display snapshots for a given LV
* Display posix filename for list-origin instead of gfid
