linux – cryptsetup 2.3.4 rpm for CentOS 7?

I have been searching for cryptsetup 2.3.4 as I want to use --perf-no_read_workqueue.

According to the release note, the option is newly added in 2.3.4.

However, my CentOS 7’s official repository only has 2.0.3. I tried to rebuild 2.3.4 myself. However, it has many dependencies that require newer versions of some libraries and expects header files and libraries in different locations, etc.

Anyone knows which repos provides cryptsetup 2.3.4?

Height of a 2-3-4 tree

Consider the following 2-3-4 tree.
2-3-4 tree
Does this have a height of 3 or 2 ?
If I count from the external nodes ie. the ones with the square boxes then height should be 3.
Not sure if they are to be included in the height as they are represented as NIL.
If they are not to be included then the height of the tree = 2
Any clarification on this.
