Hi Anshuman,

Thank you for the patch! Yet something to improve:

This series is dependent on another one which adds symbol PERF_SAMPLE_BRANCH_TYPE_SAVE
as mentioned in the cover letter. I understand the '--base' argument for git format-patch
output, but how to mention another prerequisite series before this can be built tested ?

Hi Anshuman,

git format-patch supports to set prerequisite-patch-id, kernel test robot
can parse the information and apply patch to a proper branch to test.
