Revision e72022e13d659bece2fc9cb2dd97afa67047dbca authored by Stephen Tweedie on 18 May 2005, 15:22:31 UTC, committed by Linus Torvalds on 18 May 2005, 16:10:02 UTC
Don't pass meaningless file handles to block device ioctls. The recent raw IO ioctl-passthrough fix started passing the raw file handle into the block device ioctl handler. That's unlikely to be useful, as the file handle is actually open on a character-mode raw device, not a block device, so dereferencing it is not going to yield useful results to a block device ioctl handler. Previously we just passed NULL; also not a value that can usefully be dereferenced, but at least if it does happen, we'll oops instead of silently pretending that the file is a block device, so NULL is the more defensive option here. This patch reverts to that behaviour. Noticed by Al Viro.
