Subject: [PATCH 00/18] rewrite of CB_LAYOUTRECALL and layoutstate code
Date: Thu, 4 Nov 2010 11:22:13 -0400 [thread overview]
Message-ID: <1288884151-11128-1-git-send-email-iisaman@netapp.com> (raw)
This code rewrites the layout state handling and the CB_LAYOUTRECALL paths.
It applies to Benny's current pnfs-submit branch (commit eb04948a).
Patch 01 - A session's callback patch that passes the CB_SEQUENCE info (the session in particular) up to subsequent operations. Andy is looking at issues Trond pointed out with this patch, but something very much like it will come.
02-12 - These are what smallish changes I could pull out of the rewrite. Patch 03 in particular introduces changes to refcounting that are at the heart of io drain notification.
13 - Sorry this patch is so huge, but I am simultaneously changing the stateid and RPC processing for LAYOUTGET, LAYOUTRETURN, and CB_LAYOUTRECALL, and I did not see an easy way to split them bisectably.
14 - More CB_LAYOUTRECALL changes that could be more easily split out
15-18 Andy's code that puts LAYOUTCOMMIT and LAYOUTRETURN in the same compound as CLOSE
Fred
