dump.f2fs - retrieve directory and file entries from an F2FS-formated image

dump.f2fs is available from git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-tools.git.

dump.f2fs  is  used  to retrieve f2fs metadata (usually in a disk partition).  device is the special file
       corresponding to the device (e.g.  /dev/sdXX).

       Currently, it can retrieve 1) a file given its inode number, 2) NAT entries into a file, 3)  SIT  entries
       into a file, 4) SSA entries into a file, 5) reverse information from the given block address.

       The exit code returned by dump.f2fs is 0 on success and -1 on failure.

              Specify a range presented by nids to dump NAT entries.

       -MBlockmap
              Show all the allocated block addresses given inode number.

       -sSITrange
              Specify a range presented by segment numbers to dump SIT entries.

       -aSSArange
              Specify a range presented by segment numbers to dump SSA entries.

       -bblockaddress
              Specify a block address to retrieve its metadata information.
