This lead to the formation of huge trees of snapshots all depending on a common ancestor. Hence if something bad happen to this common ancestor all the snapshot of the tree will be broken. This patch add an easy way for the user to monitor backing file ancestors count and take the good decision (streaming). in v2: lcapitulino: -Fix typo in qapi-schema.json -rename *file_ancestors_count to *backing_file_ancestors_count in v3: kwolf: qapi-schema.json backing_file_ancestors_count field not optional Add a (since 1.2) comment keep display in HMP optional Benoît Canet (3): block: create bdrv_get_backing_file_ancestors_count() block: Use bdrv_get_backing_file_ancestors_count() hmp: show the backing file ancestors count block.c | 16 ++++++++++++++++ block.h | 1 + hmp.c | 2 ++ qapi-schema.json | 9 ++++++--- 4 files changed, 25 insertions(+), 3 deletions(-) -- 1.7.9.5
