[Qemu-devel] [PATCH 0/3] Even more read-write/read-only fixes and cleanup

[Naphtali Sprei]

A comment from Christoph Hellwig made me check (and fix) some stuff.
I'm afraid there are some more callers that needs to explicitly ask for 
read-write permissions.
I'd like to get comments about that.

P.S. The qcow2 bug (I introduced) in pre-allocate showed me there's a need to 
check return value.

Naphtali Sprei (3):
  No need anymore for bdrv_set_read_only
  Ask for read-write permissions when opening files where needed
  Read-only device changed to opens it's file for read-only.
