Hi all, Latest respin of patches fixing various problems in xfsprogs. The first two patches fix some problems in the number conversion code. Patches 3-5 introduce a new structure for managing xfs runtime context. For now this simply associates a file descriptor with reported xfs geometry (and some computed values) that enable us to refactor per-ag calculations out of xfs_scrub. Later we'll use for things like graceful degradation when xfsprogs supports bulkstat v5 but the kernel doesn't, and also doing per-ag scanning operations. Patches 6-8 refactor all utilities to use common libfrog functions to retrieve the filesystem geometry, bulkstat, and inumbers. The helpers will make it easier for newer userspace to fall back to older versions of ioctls. Patch 9 strengthens mkfs's log alignment checking code. Patch 10 fixes xfs_io repair command error reporting. Patch 11 fixes libxfs-diff to handle files that are in libxfs/ in xfsprogs but still in fs/xfs/ in the kernel. Patch 12 adds a new "btheight" command to xfs_db so that we can calculate the size of each level of a theoretical btree. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=xfsprogs-5.1-fixes
