This was introduced in 3dcd15665aca80197333500a4be3900948afccc1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3dcd15665aca80197333500a4be3900948afccc1 This commit is not in the 5.12 release, but is in the latest master branch. Thank you for helping me troubleshoot this problem. I've learned a lot over the last few days. Thore
