+/* GLFS OBJECT BASED OPERATIONS
+ *
+ * The following APIs are introduced to provide an API framework that can work
+ * with gluster objects (files and directories), instead of absolute paths.
+ *
+ * The following API set can be related to the POSIX *at interfaces (like
+ * openat (2)). The intention of these APIs is to be able to operate based
+ * on parent object and looking up or creating child objects within, OR to be
+ * used on the actual object thus looked up or created, and retrieve information
+ * regarding the same.
+ *
+ * The APIs also provide for generating an opaque invariant handle to the
+ * object, that can later be used to lookup the object, instead of the regular
+ * glfs_h_* variants. The APIs that provide this behaviour are,
+ * glfs_h_extract_handle and glfs_h_create_from_handle.
+ *
+ * The object handles can be transitioned to fd based operations as supported
+ * by glfs.h calls, using the glfs_h_open call. This provides a way to move
+ * from objects to fd's akin to moving from path to fd for required operations.
+ *
+ * NOTE: The opaque invariant handle is the GFID of the object in reality, but
+ * maintained as an opaque data value, for potential internal changes to the
+ * same without impacting the caller.
+ *
+ * NOTE: Currently looking up an object can create multiple object handles to
+ * the same, i.e distinct glfs_object *. Hence each such looked up or received
+ * handle from other calls, would need to be closed. In the future, for a given
+ * object these pointers would be the same, and an ease of use API to forget all
+ * instances of this bject would be provided (instead of a per lookup close).
+ * This should not change the APIs in their current form.

+ SYNOPSIS
+
+ glfs_h_poll_upcall: Poll for upcall events given a 'glfs' object.
+
+ DESCRIPTION
+
+ This API is used to poll for upcall events stored in the
+ upcall list. Current users of this API is NFS-Ganesha.
+ In case of any event received, it will be mapped appropriately
+ into 'glfs_upcall' along with the handle('glfs_object') to be
+ passed to NFS-Ganesha.
+
+ In case of success, applications need to check the value of
+ cbk->handle to be NON NULL before processing the upcall
+ events.
+
+ PARAMETERS
+
+ @fs: glfs object to poll the upcall events for
+ @cbk: Pointer that will contain an upcall event for use by the application.
+ Application is responsible for free'ing the structure with glfs_free().
+
+ RETURN VALUES
+
+ 0 : Success.
+ -1 : Error condition, mostly due to out of memory.

+ * - The groups once set, need to be unset by setting the size to 0 (in which
