Hi Al,
Jeff Chua reported a while ago that BLKFLSBUF returns EBUSY on a RAM disk
that was obtained via initrd. I think the problem is that the effect of
the blkdev_open(out_inode, ...) in drivers/block/rd.c:rd_load_image is
not undone at the end. I've attached a patch for 2.4.0-test11-pre7 that
seems to solve the problem. Since I'm not quite sure I understand the
reference counting rules there, I would appreciate your comment.
Thanks,
- Werner
