[Qemu-devel] [PATCH v2 0/5] Remove bdrv_read() and bdrv_write()

[Alberto Garcia <berto@igalia.com>]

Hi,

this API only had a few users left so it can be easily removed.

Regards,

Berto

v2:
- Patch 2: Add QEMU_BUILD_BUG_ON(sizeof(VdiHeader) != 512) [Kevin]
           Correct size parameter in bdrv_pwrite() call [Kevin]
           Return 0 on success, never a positive number [Kevin]
- Patch 3: Check that the return values of bdrv_pread()/bdrv_pwrite()
           are strictly < 0 for errors, not simply != 0 [Kevin]
- Patch 4: Reuse the documenation of bdrv_write() for bdrv_pwrite()

v1: https://lists.gnu.org/archive/html/qemu-block/2019-04/msg00832.html
