The patch for LU-4239 with commit 825570b0b03e0fd70a removed the limit of a path with 100 subdirectories or more and added sanity test 162c to test this. This patch was added in Lustre 2.7.0 in tag 2.6.92. The test needs a check the server version before running. If the server is 2.6.92 or above, run the test. If not, skip it.

I'll upload a patch for this.
