I'm *guessing* these are all some underlying issue where keyrings aren't being given all the needed permissions anymore. But just FYI, David had said he's on vacation with no laptop or email access for 2 weeks starting from Sunday (3 days ago). So I don't think you can expect a quick fix from him. I was planning to look into this to fix the fscrypt tests, but it might be a few days before I get to it. And while I'm *guessing* it will be a simple fix, it might not be. So I can't speak for David, but personally I'm fine with the commits being reverted for now. I'm also unhappy that the new keyctl KEYCTL_GRANT_PERMISSION doesn't have any documentation or tests. (Which seems to be a common problem with David's work... None of the new mount syscalls in v5.2 have any tests, for example, and the man pages are still work-in-progress and last sent out for review a year ago, despite API changes that occurred before the syscalls were merged.) - Eric
