[Qemu-devel] [PATCH V5 0/4] Show backing file depth in HMP and QMP |

From: Benoît Canet <address@hidden>
In some setups many backing files and snapshot are chained.
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 ++
