[PATCH 0/7] Implement bdrv_{pread, pwrite, pwrite_sync, pwrite_zeroes}() using generated_co_wrapper

Posted by Alberto Faria 1 year, 11 months ago

Start by making the interfaces of analogous non-coroutine and coroutine
functions consistent with each other, then implement the non-coroutine
ones using generated_co_wrapper.

For the bdrv_pwrite_sync() case, also add the missing
bdrv_co_pwrite_sync() function.

Alberto Faria (7):
  block: Add a 'flags' param to bdrv_{pread,pwrite,pwrite_sync}()
  block: Change bdrv_{pread,pwrite,pwrite_sync}() param order
  block: Make bdrv_{pread,pwrite}() return 0 on success
  block: Make bdrv_co_pwrite() take a const buffer
  block: Make 'bytes' param of bdrv_co_{pread,pwrite,preadv,pwritev}()
    an int64_t
  block: Implement bdrv_{pread,pwrite,pwrite_zeroes}() using
    generated_co_wrapper
  block: Add bdrv_co_pwrite_sync()
