I commited my fix up via "git commit -a --amend". Unfortunately, I didn't realize I had some changes I was testing in the module code, and those changes were applied to Divya's patch as well. This reverts the accidental updates to the module code. Cc: Jessica Yu Cc: Divya Indi Reported-by: Peter Zijlstra Fixes: e585e6469d6f ("tracing: Verify if trace array exists before destroying it.")
