No, blkid=0, level=0 is a different block from blkid=0 level=1. If
you draw the tree of blocks, each level will start with blkid 0, then 1,
2, etc. See traverse_visitbp(), the "BP_GET_LEVEL(bp) > 0" section, for
more details.

Hello,
Do the logical block id-s of a given dnode form a single id space, or are they
layered per level?
In other words, do all blocks, regardless of their level belong to the same id
space 0..n
or is each level assigned its own set ob block id-s 0..n?
I am guessing it is a single id space per dnode, but I notice many of the block
traversal
primitives take both the id and the level.
Tia for clarifying this,
Steve
