Hi all, This patch set goes along with the fourth revision of an RFC adding to XFS kernel support for tracking reverse-mappings of physical blocks to file and metadata; and support for mapping multiple file logical blocks to the same physical block, more commonly known as reflinking. The two patches in this series document the clone, clone_range, and dedupe ioctls in the form of man pages. The patch set is based on a whole pile of proposed patches against the current (4.4-rc5) upstream kernel; the ioctls are simply hoisted version of the private btrfs ioctls. If you're going to start using this mess, you probably ought to just pull from my github trees for kernel[1], xfsprogs[2], and xfstests[3]. See also the xfs-docs[4] and manpage[5] updates. This is an extraordinary way to eat your data. Enjoy! Comments and questions are, as always, welcome. --D [1] https://github.com/djwong/linux/tree/for-dave [2] https://github.com/djwong/xfsprogs/tree/for-dave [3] https://github.com/djwong/xfstests/tree/for-dave [4] https://github.com/djwong/xfs-documentation/tree/for-dave [5] https://github.com/djwong/man-pages/commits/for-mtk -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
