Thin-arbiter module makes use of 'pending-xattr' name for the translator
as the filename which gets created in thin-arbiter node. By making this
unique, we can host single thin-arbiter node for multiple clusters.

Problem:
heal-info code assumes that all indices in xattrop directory
definitely need heal. There is one corner case.
The very first xattrop on the file will lead to adding the
gfid to 'xattrop' index in fop path and in _cbk path it is
removed because the fop is zero-xattr xattrop in success case.
These gfids could be read by heal-info and shown as needing heal.

Fix:
Check the pending flag to see if the file definitely needs or
not instead of which index is being crawled at the moment.

Problem: At the time of coming up one server node(1x3) after reboot
client is unmounted.The client is unmounted because a client
is getting AUTH_FAILED event and client call fini for the graph.The
client is getting AUTH_FAILED because brick is not attached with a
graph at that moment

Solution: To avoid the unmounting the client graph throw ENOENT error
          from server in case if brick is not attached with server at
          the time of authenticate clients.

The quota_log_helper() function applies memory
for path through inode_path(), should be GF_FREE().

Glusterfs client process has memory leak if create serveral files under one folder, and delete the folder.
According to statedump, the ref counts of readdir-ahead is bigger than zero in the inode table. Readdir-ahead get parent inode by inode_parent in rda_mark_inode_dirty when each rda_writev_cbk,the inode ref count of parent folder will be increased in inode_parent, but readdir-ahead do not unref it later.
The correction is unref the parent inode at the end of rda_mark_inode_dirty

We need to safe-guard against possible zero'ing out of iatt
structure in acl ctx, which can cause many issues.

Null character string is a valid xattr value in file system. But for
those xattrs processed by md-cache, it does not update its entries if
value is null('\0'). This results in ENODATA when those xattrs are
queried afterwards via getxattr() causing failures in basic operations
like create, copy etc in a specially configured Samba setup for Mac OS
clients.

On the other side snapview-server is internally setting empty string("")
as value for xattrs received as part of listxattr() and are not intended
to be cached. Therefore we try to maintain that behaviour using an
additional dictionary key to prevent updation of entries in getxattr()
and fgetxattr() callbacks in md-cache.

Changes in locks xlator:
Added support for per-domain inodelk count requests.
Caller needs to set GLUSTERFS_MULTIPLE_DOM_LK_CNT_REQUESTS key in the
dict and then set each key with name
'GLUSTERFS_INODELK_DOM_PREFIX:<domain name>'.
In the response dict, the xlator will send the per domain count as
values for each of these keys.

Changes in AFR:
Replaced afr_selfheal_locked_inspect() with afr_lockless_inspect(). Logic has
been added to make the latter behave same as the former, thus not
breaking the current heal info output behaviour.

The fd processing loops in the
dht_migration_complete_check_task and the
dht_rebalance_inprogress_task functions were unsafe
and could cause an open to be sent on an already freed
fd. This has been fixed.
