adeb0c7a | 4 | Subject: [PATCH 32/48] vma: better driver guessing for bdrv_open |
2c75dbed WB |
5 | |
6 | Only use 'raw' when the file actually ends with .raw and | |
7 | no protocol has been specified. With protocol pass the | |
8 | BDRV_O_PROTOCOL flag to tell bdrv_fill_options() to take it | |
9 | into account. | |
