Subject: [PATCH 00/22] rewrite of CB_LAYOUTRECALL and layoutstate code, try 2
Date: Fri, 12 Nov 2010 03:48:22 -0500 [thread overview]
Message-ID: <1289551724-18575-1-git-send-email-iisaman@netapp.com> (raw)
This is version 2 of code that rewrites the layout state handling and
the CB_LAYOUTRECALL paths, incorporating suggestions from Benny, as
well as some compile fixes for the non-v4.1 case, and reordering
the patches to put the simpler, less intrusive changes first.
I'm not entirely happy with the non-v4.1 compile fixes I added, but
they are a starting point.
It applies to Benny's current pnfs-submit branch (commit eb04948a).
patches 01-05 are straightforward tweaking preparing for the bigger changes
patches 06-08 modify CB_COMPUND processing to pass the CB_SEQUENCE info (the session in particular) up to subsequent operations.
patches 09-15 are more substantial changes affecting refcounting and blocking.
patches 16-17 are the point of it all, the rewrite of the stateid and race handling for LAYOUTGET, LAYOUTRETURN, and CB_LAYOUTRECALL
patches 18-22 are Andy's code that puts LAYOUTCOMMIT and LAYOUTRETURN in the same compound as CLOSE
