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.
