of blocks used by a requested list of inodes. For example, to list the blocks referenced by your kernel: guest_12 % df / Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/gpt/rootfs 20307196 10707336 7975288 57% / guest_12 % ls -i /boot/kernel/kernel 160603 /boot/kernel/kernel guest_12 % ./prtblknos /dev/gpt/rootfs 160603 160603: lbn 0-7 blkno 3217584-3217647 lbn 8-11 blkno 3217864-3217895 distance 216 First-level indirect, blkno 3217896-3217903 distance 0 lbn 12-19 blkno 3217904-3217967 distance 8 lbn 20-75 blkno 3251816-3252263 distance 33848 lbn 76-83 blkno 3252368-3252431 distance 104 lbn 84-91 blkno 3252464-3252527 distance 32 lbn 92-852 blkno 3252896-3258983 distance 368 Each contiguous range of blocks is printed on a line. The distance metric is the size of the gap from the end of the previous set of blocks to the beginning of the next set of blocks. Short distances are desirable.
