Hi all, This series enables xfs_repair to add select features to existing V5 filesystems. Specifically, one can add free inode btrees, reflink support, and reverse mapping. 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=upgrade-older-features fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=upgrade-older-features --- include/libxfs.h | 1 man/man8/xfs_admin.8 | 21 +++++ repair/globals.c | 3 + repair/globals.h | 3 + repair/phase2.c | 229 ++++++++++++++++++++++++++++++++++++++++++++++++++ repair/rmap.c | 8 +- repair/xfs_repair.c | 33 +++++++ 7 files changed, 294 insertions(+), 4 deletions(-)
