[Qemu-devel] [PATCH v2 0/5] block: preparatory patches for scatter/gathe

From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH v2 0/5] block: preparatory patches for scatter/gather support
Date: Fri, 16 Sep 2011 16:39:59 +0200

These patches are preparatory work for supporting scatter/gather in
the SCSI subsystem.  Since there would be no HBA actually using it,
I am just posting the cleanups, and the fix for CVE-2011-3346 (buffer
overflow in the handling of READ CAPACITY 16) that comes for free
with the last patch.

v1->v2: made to_dev a bool; fixes in patch 3

Paolo Bonzini (5):
  dma-helpers: rename is_write to to_dev
  dma-helpers: allow including from target-independent code
  dma-helpers: rewrite completion/cancellation
  scsi-disk: commonize iovec creation between reads and writes
  scsi-disk: lazily allocate bounce buffer
