From 0db6e54a8a2c6e16780356422da671b71f862341 Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Fri, 17 Apr 2015 19:49:50 -0400 Subject: qapi: Add optional field "name" to block dirty bitmap This field will be set for user created dirty bitmap. Also pass in an error pointer to bdrv_create_dirty_bitmap, so when a name is already taken on this BDS, it can report an error message. This is not global check, two BDSes can have dirty bitmap with a common name. Implemented bdrv_find_dirty_bitmap to find a dirty bitmap by name, will be used later when other QMP commands want to reference dirty bitmap by name. Add bdrv_dirty_bitmap_make_anon. This unsets the name of dirty bitmap.
