[Qemu-devel] [PATCH 0/5] data integrity fixes V2

[Christoph Hellwig]

respin of the data integrity series.  Major changes since the first
version:

 - split ide use of bdrv_aio_flush into a separate patch
 - added a qemu_fdatasync helper that falls back to fsync if needed
 - enable barriers for data=writeback

The last might be a bit controversial, but I can't find a workload where
it really causes major regressions.  And then you can still mount your
guest filesystems with barrier=0/nobarrier (like the ext3 default) and
this code won't ever be called.
