[Qemu-devel] [PATCH v13 0/6] qcow2, raw: add preallocation=full |

This series adds preallocation=full to qcow2 and raw:
Option preallocation=full preallocates disk space for image by calling
posix_fallocate() if it's available, otherwise by writing zeros to
disk.
Max, Eric, Fam,
I removed your Reviewed-by line in all patches since they've been
changed. You're welcome to review again!
changes to v12:
- remove dependence on minimal_blob_size() (patch 6)
- remove preallocation=falloc. (patch 4)
- preallocation=full tries posix_fallocate() first then writing
zeros (patch 5)
- round up file size for all formats (patch 1)
- avoid converting file size for more formats (patch 2)
Hu Tao (5):
block: round up file size to nearest sector
block: don't convert file size to sector size
qapi: introduce PreallocMode and a new PreallocMode full.
raw-posix: Add full preallocation option
qcow2: Add full preallocation option
Peter Lieven (1):
rename parse_enum_option to qapi_enum_parse and make it public
