linux-kselftest-5.8-rc2

Browse Source 
This Kselftest update for Linux 5.8-rc2 consists of:
 
 - ftrace "requires:" list for simplifying and unifying requirement
   checks for each test case, adding "requires:" line instead of
   checking required ftrace interfaces in each test case.
 - a minor spelling correction patch
