[Qemu-devel] [PATCH v3 01/14] block: Lift some BDS functions to the BlockBackend |
Date: |
Mon, 26 Jan 2015 10:00:31 -0500 |
Create the blk_* counterparts for the following bdrv_* functions (which
make sense to call on the BlockBackend level):
- bdrv_co_write_zeroes()
- bdrv_write_compressed()
- bdrv_truncate()
- bdrv_discard()
- bdrv_load_vmstate()
- bdrv_save_vmstate()
