Hi all, below are backports up to (almost) 4.12-rc4 for XFS. I've selected all clear bugfixes for reported bugs. One patch is a little odd as it's a subset of a patch that went into mainline, which included a bit of infrastructure in addition to the new feature, and we only need the infrastructure for stable. Also a fs/iomap.c fix for code only used by XFS is included. [sorry for the resend, one commit contained an existing stable@ Cc with a "#" sign in it that made the mail server throw up. This also means you might get these commits twice, but the whole set here is one that passed xfstests testing]
