switch raw block driver from "raw.o" to "raw_bsd.o"
"Incoming" function prototypes and "outgoing" function calls must match reality. Implemented using the "struct BlockDriver" definition in "include/block/block_int.h", and gcc errors & warnings. v1->v2: On 08/20/13 09:51, Kevin Wolf wrote: > Am 18.08.2013 um 16:29 hat Paolo Bonzini geschrieben: >> Il 16/08/2013 16:15, Laszlo Ersek ha scritto: >>> +static int raw_reopen_prepare(BDRVReopenState *reopen_state, >>> + BlockReopenQueue *queue, Error **errp) >>> { >>> - return bdrv_reopen_prepare(bs->file); >>> + BDRVReopenState tmp = *reopen_state; >>> + >>> + tmp.bs = tmp.bs->file; >>> + return bdrv_reopen_prepare(&tmp, queue, errp); >>> } >> >> This should just return zero, my fault. > > Which is because bdrv_reopen_queue() already queues bs->file for reopen. > The simple return 0; implementation is shared by all other format drivers > that support reopening images.
