Hi all.
v2: fix build error, gcc things that some variables may be used
uninitialized (actually they didn't).
These series is a replacement for "qemu-img check: unallocated size"
series.
There was a question, should we account allocated clusters in qcow2 but
actually holes in underalying file as allocated or not. Instead of
hiding this information in one-number statistic I've decided to print
the whole information, 5 numbers:
For allocated by top-level format driver (qcow2 for ex.) clusters, 3
numbers: number of bytes, which are:
- allocated in underlying file
- holes in underlying file
- after end of underlying file
To account other areas of underlying file, 2 more numbers of bytes:
- unallocated by top-level driver but allocated in underlying file
- unallocated by top-level driver and holes in underlying file
Vladimir Sementsov-Ogievskiy (4):
block: add bdrv_get_format_alloc_stat format interface
qcow2: add .bdrv_get_format_alloc_stat
qemu-img check: add format allocation info
qemu-img check: improve dump_human_format_alloc_info
