gfapi: APIs to store and process upcall notifications received
In case of any upcall cbk events received by the protocol/client, gfapi will be notified which queues them up in a list (<gfapi_cbk_upcall>). Applicatons are responsible to provide APIs to process & notify them in case of any such upcall events queued. Added a new API which will be used by Ganesha to repeatedly poll for any such upcall event notified (<glfs_h_poll_upcall>). A new test-file has been added to test the cache_invalidation upcall events. Below link has a writeup which explains the code changes done - URL: https://soumyakoduri.wordpress.com/2015/02/25/glusterfs-understanding-upcall-infrastructure-and-cache-invalidation-support/ Change-Id: Iafc6880000c865fd4da22d0cfc388ec135b5a1c5 BUG: 1200262 Signed-off-by: Soumya Koduri <skoduri@redhat.com> Reviewed-on: http://review.gluster.org/9536 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com>
