Hi all, This is the eighth revision of a patchset that adds to XFS kernel support for mapping multiple file logical blocks to the same physical block (reflink/deduplication), implements the beginnings of online metadata scrubbing and preening, and implements reverse mapping for the realtime device. There shouldn't be any incompatible on-disk format changes, pending a thorough review of the patches within. The first several patches in this series fix various minor errors in a variety of existing tests. The biggest change fixes xfs_db usage to work when an external log is specified. The new tests in this series ensure that xfs_fsr works with files having a high extent count and reverse mapping enabled. Next come more tests for the existing XFS rmap functionality, tests for the realtime rmap patches against XFS, some quick sanity checks for the proposed GETFSMAP ioctl, and tests of shared extent reporting via GETBMAPX. If you're going to start using this mess, you probably ought to just pull from my github trees for kernel[1], xfsprogs[2], xfstests[3], xfs-docs[4], and man-pages[5]. The kernel patches in the git trees should apply to 4.8-rc3; xfsprogs patches to for-next; and xfstest to master. The patches have been xfstested with x64, ppc64, and armhf; all tests in the clone and rmap groups pass. AFAICT they don't cause any new failures for the 'auto' group. 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/djwong-devel [2] https://github.com/djwong/xfsprogs/tree/djwong-devel [3] https://github.com/djwong/xfstests/tree/djwong-devel [4] https://github.com/djwong/xfs-documentation/tree/djwong-devel [5] https://github.com/djwong/man-pages/tree/djwong-devel From: "Darrick J. Wong" <darrick.wong@xxxxxxxxxx> Subject: [PATCH v8 00/13] xfstests: fixes and new tests for rmap/reflink/etc Hi all, This is the eighth revision of a patchset that adds to xfstests support for testing reverse-mappings of physical blocks to file and metadata (rmap); support for testing multiple file logical blocks to the same physical block (reflink); and implements the beginnings of online metadata scrubbing. The first eleven tests fix various bugs in existing reflink and rmap tests, most of which were a result of not using helpers when I should have. After that, there are new tests to make sure that we can't clone_range across mountpoints; test to make sure that swapext works with many extents on a rmap filesystem; and tests for realtime reverse-mapping. There are also revised patches for testing xfs_repair's ability to rebuild filesystem indices correctly, and to run xfs_scrub during each test. If you're going to start using this mess, you probably ought to just pull from my github trees for kernel[1], xfsprogs[2], xfstests[3], and documentation[4]. The kernel patches should apply to 4.8-rc3; xfsprogs patches to for-next; and xfstest to master. The patches have been xfstested with x64, i386, armv7l, and ppc64. AFAICT these don't cause any new failures for the 'auto' group. This is an extraordinary way to eat your data. Enjoy!
