[Qemu-devel] [PATCH RFC v11 0/6] qcow2, raw: add preallocation=full and preallocation=falloc |

Kevin,
This is v11 series for you to check how the series depends on Max's
minimal_blob_size(). I'm aware that you rejected the calculation of
metadata size, but posting this series so that you can comment on it.
This series depends on patches 1-3 of Max's series 'qemu-img: Implement
commit like QMP'.
Option preallocation=full preallocates disk space for image by writing
zeros to disk, this ensures disk space in any cases.
Option preallocation=falloc preallocates disk space by calling
posix_fallocate(). This is faster than preallocation=full.
The series is also at https://github.com/taohu/qemu/commits/preallocation-v11
for you to check out.
changes to v10:
- PreallocMode is moved from file qapi-schema.json to qapi/block-core.json
- introdues preallocation=falloc, no changes to preallocation=metadata
- using minimal_blob_size() to calculate metadata size for qcow2
- indentation fix in file blockdev.c
Hu Tao (6):
block: round up file size to nearest sector
raw, qcow2: don't convert file size to sector size
rename parse_enum_option to qapi_enum_parse and make it public
qapi: introduce PreallocMode and a new PreallocMode full.
raw-posix: Add falloc and full preallocation option
qcow2: Add falloc and full preallocation option
