From 985903bb3a6d98623360ab6c855417f638840029 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 10 Dec 2009 23:52:11 +0000 Subject: dm snapshot: add allocated metadata to snapshot status Add number of sectors used by metadata to the end of the snapshot's status line. Renamed dm_exception_store_type's 'fraction_full' to 'usage'. Renamed arguments to be clearer about what is being returned. Also added 'metadata_sectors'.
