Soumya Koduri 491ff40a7a gfapi: Unblock epoll thread for upcall processing 
With commit#ad35193,we have made changes to offload
processing upcall notifications to synctask so as not
to block epoll threads. However seems like the issue wasnt
fully addressed.

In "glfs_cbk_upcall_data" -> "synctask_new1" after creating synctask
if there is no callback defined, the thread waits on synctask_join
till the syncfn is finished. So that way even with those changes,
epoll threads are blocked till the upcalls are processed.

Hence the right fix now is to define a callback function for that
synctask "glfs_cbk_upcall_syncop" so as to unblock epoll/notify threads
completely and the upcall processing can happen in parallel by synctask
threads.

Gluster

Gluster is a software defined distributed storage that can scale to several petabytes. It provides interfaces for object, block and file storage.

Development

Contributions to gluster in the form of patches and new feature additions can be made by following steps outlined at Developers Guide.

Documentation

The Gluster documentation can be found at Gluster Docs.

Deployment

Quick instructions to build and install can be found in INSTALL file.

Testing

GlusterFS source contains some functional tests under tests/ directory. All these tests are run against every patch submitted for review. If you want your patch to be tested, please add a .t test file as part of your patch submission. You can also submit a patch to only add a .t file for the test case you are aware of.

To run these tests, on your test-machine, just run ./run-tests.sh. Don't run this on a machine where you have 'production' glusterfs is running, as it would blindly kill all gluster processes in each runs.

If you are sending a patch, and want to validate one or few specific tests, then run a single test by running the below command.

  bash# /bin/bash ${path_to_gluster}/tests/basic/rpc-coverage.t

You can also use prove tool if available in your machine, as follows.

  bash# prove -vmfe '/bin/bash' ${path_to_gluster}/tests/basic/rpc-coverage.t
