Subject: [Qemu-devel] [PATCH 0/3] qcow2: Fix preallocated truncation
Date: Mon,  9 Oct 2017 23:55:30 +0200	[thread overview]
Message-ID: <20171009215533.12530-1-mreitz@redhat.com> (raw)

There are (at least...) two bugs in preallocated truncation, which this
series fixes.

Both would have been apparent if the the related iotest had used the
default cluster size in addition to 512 byte clusters, but alas, it did
not.  This is remedied by patch 3 of this series.


Max Reitz (3):
  qcow2: Fix unaligned preallocated truncation
  qcow2: Always execute preallocate() in a coroutine
  iotests: Add cluster_size=64k to 125
