From 2a4561ef08b8be3b7d79b951252e87ba8f987120 Mon Sep 17 00:00:00 2001 From: Soumya Koduri Date: Mon, 16 Feb 2015 11:47:58 +0530 Subject: 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 (). 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 (). 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 Reviewed-on: http://review.gluster.org/9536 Tested-by: Gluster Build System Reviewed-by: Kaleb KEITHLEY --- rpc/xdr/src/glusterfs3.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'rpc') diff --git a/rpc/xdr/src/glusterfs3.h b/rpc/xdr/src/glusterfs3.h index b3ee267b64d..c2fa15f9e79 100644 --- a/rpc/xdr/src/glusterfs3.h +++ b/rpc/xdr/src/glusterfs3.h @@ -279,4 +279,17 @@ gf_proto_upcall_from_upcall (gfs3_upcall_req *gf_up_req, gf_up_req->flags = gf_up_data->flags; gf_up_req->expire_time_attr = gf_up_data->expire_time_attr; } + +static inline void +gf_proto_upcall_to_upcall (gfs3_upcall_req *gf_up_req, + struct gf_upcall *gf_up_data) +{ + if (!gf_up_req || !gf_up_data) + return; + + memcpy (gf_up_data->gfid, gf_up_req->gfid, 16); + gf_up_data->event_type = gf_up_req->event_type; + gf_up_data->flags = gf_up_req->flags; + gf_up_data->expire_time_attr = gf_up_req->expire_time_attr; +} #endif /* !_GLUSTERFS3_H */ -- cgit
