Could PTRACE_ATTACH be handled without SAFE_PTRACE() so that EPERM caused
by Yama policy can be reported as TCONF? With ptrace_scope=3 Linux denies
every attach, including requests from root, and the wrapper converts this
expected policy denial to TBROK before the test reaches PTRACE_POKEDATA.

Could this entry instead be placed in a .gitignore in the hugemmap leaf
directory? LTP requires new test binaries to be ignored in their own test
directory rather than from a parent directory.

Verdict - Needs revision
