Summary: Followed guide here https://www.internalfb.com/intern/wiki/Linting/License_Lint/ to add fbcode/hermetic_infra/** code to license linter. As we have parts of our code shipped as Open Source it's important to get this automated This diff is updating existing file's licenses to not get conflict after lint rule enablement Reviewed By: jasonwhite Differential Revision: D40674080 fbshipit-source-id: da6ecac036f8964619cf7912058f3a911558e7b1
