Problem:
glfsheal operates based on mount's volfile which doesn't have iamshd flag due
to which this->itable is NULL, this leads to "inode not found" logs in glfsheal
logs.
Fix:
Ec only allocates itable with 10 inodes, so allocating this->itable in all
cases in init.

Add a policy in ec to performs reads from same bricks as long as they
are good. Based on the gfid of the file/directory it determines the
bricks to be considered for reading.

Problem:
New lock could come at the time timer is on the way to unlock. This was leading
to crash in timer thread because thread executing new lock can free up the
timer_link->fop and then timer thread will try to access structures already
freed.
Fix:
If the timer event is fired, set lock->release to true and wait for unlock to
complete.
Thanks to Xavi and Bhaskar for helping in confirming that this race is the RC.
Thanks to Kritika for pointing out and explaining how Avati's patch can be used
to fix this bug.

Problem : User can set wrong values for cluster.heal-timeout
using cli. Any value like string, negative numbers
or 0 could be set.
Solution : Check the value given by user. It should be numerical,
non negative and within the range.

When a delayed lock is pending, a graph switch doesn't correctly
terminate it. This means that the update of version and size xattrs
is lost, causing EIO errors.
This patch handles GF_EVENT_PARENT_DOWN event to correctly finish
pending udpdates before completing the graph switch.

If both dicts are NULL then equal. If one of the dicts is NULL but the other
has only ignorable keys then also they are equal. If both dicts are non-null
then check if for each non-ignorable key, values are same or not. value_ignore
function is used to skip comparing values for the keys which must be present in
both the dictionaries but the value could be different.
geo-rep's stime xattr doesn't need to be present in list xattr but when
getxattr comes on stime xattr even if there aren't enough responses with the

Problem:
gf_deitransform returns the glbal client-id in the complete graph. So except
for the first disperse subvolume under dht, all the other disperse subvolumes
will return a client-id greater than ec->nodes, so readdir will always error
out in those subvolumes.
Fix:
Get the client subvolume whose client-id matches the client-id returned by
gf_deitransform of offset.

- Changed the implementation of marker xattr handling to take just a
function which populates important data that is different from
default 'gauge' values and subvolumes where the call needs to be
wound.
- Removed duplicate code I found while reading the code and moved it to
cluster_marker_unwind. Removed unused structure members.
- Changed dht/afr/stripe implementations to follow the new implementation
- Implemented marker xattr handling for ec.

This patch introduces the changes required in ec xlator to handle
index/full heal.
Index healer threads:
Ec xlator start an index healer thread per local brick. This thread keeps
waking up every minute to check if there are any files to be healed based on
the indices kept in index directory. Whenever child_up event comes, then also
this index healer thread wakes up and crawls the indices and triggers heal.
When self-heal-daemon is disabled on this particular volume then the healer
thread keeps waiting until it is enabled again to perform heals.
Full healer threads:
Ec xlator starts a full healer thread for the local subvolume provided by
glusterd to perform full crawl on the directory hierarchy to perform heals.
Once the crawl completes the thread exits if no more full heals are issued.
Changed xl-op prefix GF_AFR_OP to GF_SHD_OP to make it more generic.

Problem:
When all the bricks are down at the time of mounting the volume, then mount
command hangs.
Fix:
1. Ignore all CHILD_CONNECTING events comming from subvolumes.
2. On timer expiration (without enough up or down childs) send
CHILD_DOWN.
3. Once enough up or down subvolumes are detected, send the appropriate event.
When rest of the subvols go up/down without changing the overall
ec-up/ec-down send CHILD_MODIFIED to parent subvols.

For volumes with replicate, disperse xlators, self-heal daemon should do
healing. This patch provides enable/disable functionality for the xlators to be
part of self-heal-daemon. Replicate already had this functionality with
'gluster volume set cluster.self-heal-daemon on/off'. But this patch makes it
uniform for both types of volumes. Internally it still does 'volume set' based
on the volume type.

This patch significantly improves performance of read/write
operations on a dispersed volume by reusing previous inodelk/
entrylk operations on the same inode/entry. This reduces the
latency of each individual operation considerably.
Inode version and size are also updated when needed instead
of on each request. This gives an additional boost.
