Message

Paolo Bonzini June 1, 2023, 11:51 a.m. UTC 
The value of the bdrv_file_open is sometimes checked to distinguish
protocol and format drivers, but apart from that there is no difference
between bdrv_file_open and bdrv_open.

However, they can all be distinguished by the non-NULL .protocol_name
member.  Change the checks to use .protocol_name instead of .bdrv_file_open,
and unify the two callbacks.

v1->v2: fix bisectability

Paolo Bonzini (3):
  block: make assertion more generic
  block: do not check bdrv_file_open
  block: remove separate bdrv_file_open callback
