Hi Linus,
linux-2.5.28/drivers/block_dev.c has a new do_open that broke
initial ramdisk support, because it now requires devices that "manually"
set bdev->bd_openers to set bdev->bd_inode->i_size as well. The
following single line patch, suggested by Russell King, fixes the
problem.
There does not appear to be anyone acting as maintainer for
rd.c, so I posted to lkml yesterday to ask if anyone objected to my
submitting the patch to you, and I also emailed the message to Russell
King and Al Viro. Nobody has complained. I have been running the
patch for almost a day without problems.
Please apply. Thanks in advance.
