From b3b515bbd689ba3937cac2dd3fc55057f8c50329 Mon Sep 17 00:00:00 2001 From: Aruna Balakrishnaiah Date: Fri, 16 Aug 2013 13:52:47 -0700 Subject: pstore: Add new argument 'compressed' in pstore write callback Addition of new argument 'compressed' in the write call back will help the backend to know if the data passed from pstore is compressed or not (In case where compression fails.). If compressed, the backend can add a tag indicating the data is compressed while writing to persistent store.
