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 depth and take the good decision (streaming). in v2: lcapitulino: -Fix typo in qapi-schema.json -rename *file_ancestors_count to *backing_file_ancestor_count in v3: kwolf: qapi-schema.json backing_file_ancestor_count field not optional Add a (since 1.2) comment keep display in HMP optional in v4: eblake: rename backing_file.ancestors.count to backing.file.depth in qapi-schema.json use - instead of _ Fix json docstring in v5: eblake: ditch completely the word ancestor in comment Add the corresponding patch to qmp-commands.hx Benoît Canet (4): block: create bdrv_get_backing_file_depth() block: Use bdrv_get_backing_file_depth() qmp: Add backing-file-depth to qmp-commands.hx hmp: show the backing file depth block.c | 16 ++++++++++++++++ block.h | 1 + hmp.c | 2 ++ qapi-schema.json | 9 ++++++--- qmp-commands.hx | 2 ++ 5 files changed, 27 insertions(+), 3 deletions(-) -- 1.7.9.5
