The kernel patch series just sent (Subject: "Btrfs: scrub: print path to corrupted files and trigger nodatasum fixup") introduces two new ioctls to do in-kernel filesystem path construction. This series provides the corresponding userspace changes, adding two new commands to the btrfs utility: -- btrfs resolve inode [-v] <inode> <path> resolves an <inode> to all filesystem paths local to the fs mounted at <path>. -v print count of returned and missed paths btrfs resolve logical [-v] [-P] <logical> <path> resolves a <logical> address to all filesystem paths in the file system mounted at <path> and all its subvolumes. -v print count of returned and missed inode/offset/root triples -P do not resolve the path but stop after finding all inodes at this logical address and print them instead -- These patches are based on Hugo's current integration branch. Please try them out and report bugs here. I'll send an update to the manpages later. -Jan Jan Schmidt (2): btrfs-list: split list_subvols added ioctls and commands to resolve inodes and logical addresses btrfs-list.c | 139 ++++++++++++++++++++++++++++++++++------------ btrfs.c | 10 +++ btrfs_cmds.c | 177 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ btrfs_cmds.h | 3 + ioctl.h | 29 ++++++++++ 5 files changed, 323 insertions(+), 35 deletions(-) -- 1.7.3.4 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
