This patch is against 4.5-rc6 and hasn't changed much in months. The new BLKZEROOUT ioctl has the same semantics as the old one, but it invalidates the page cache to prevent surprising results, just like how dio writes invalidate page cache. I've incorporated all the feedback I've received into these patches, but haven't heard yea or nay or anything at all from the maintainer. Will someone please pick this up for 4.6? Comments and questions are, as always, welcome. --D
