From 759048ac20174b34fa7a593f4da2e7fed34e599c Mon Sep 17 00:00:00 2001 From: Bharata B Rao Date: Tue, 27 Jan 2015 09:35:00 +0530 Subject: [PATCH] pc: Fix DIMMs capacity calculation pc_existing_dimms_capacity() is returning DIMMs count rather than capacity. Fix this to return the capacity. Also consider only realized devices for capacity calculation. Signed-off-by: Bharata B Rao Reviewed-by: Igor Mammedov Reviewed-by: Michael S.
