Subject: resend: BLKGETSIZE64 patch
X-Mailing-List: linux-kernel@vger.kernel.org
Hello,
This patch hasn't turned up in -pre6, so here's another retransmit. The
patch is needed so that further testing of the 64 bit blkoff_t patches
doesn't result in another ioctl conflict fiasco, as well as preventing
new tools from causing the kernel to emit various warning printks. Also,
the patch removes unneeded error checking in a number of places, namely
resulting in a -EFAULT instead of -EINVAL for a NULL argument to BLKGETSIZE.
