From 5fa3142da14b162f30e4781ff17e1926c47f28fb Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Sun, 6 Sep 2015 17:05:42 +0800 Subject: [PATCH] virtio-blk: Allow extended partitions This will allow up to DISK_MAX_PARTS (256) partitions, with for example GPT in the guest. Otherwise, the partition scan code will only discover the first 15 partitions. Signed-off-by: Fam Zheng Signed-off-by: Michael S.
