[Qemu-devel] [PATCH 0/8] finish coroutinization of drivers |

Drivers that only implement the bdrv_read and bdrv_write callbacks
were unwillingly converted to be reentrant when bdrv_read and
bdrv_write were changed to always create coroutines. So,
we need locks aroudn read and write operations.
This series does this (patches 4-6) and removes the flush/discard
callbacks that, as it turns out, are really duplicates of co_flush
and co_discard (patches 7-8).
Patches 1-3 are fixes/cleanups that I discovered while testing.
Paolo Bonzini (8):
vpc: detect floppy disk geometries
vmdk: fix return values of vmdk_parent_open
vmdk: clean up open
block: add a Rwlock to synchronous read/write drivers
block: take lock around bdrv_read implementations
block: take lock around bdrv_write implementations
block: change flush to co_flush
block: change discard to co_discard
