Hi, not sure whether I may have missed a response that didn’t make it back to me or any of the lists. Just in case, because the CC didn’t include the original addendum I made to my report: Addendum: I’ve checked kernel changelogs since then but didn’t find anything that I could relate to this aside from *maybe* dfda2a5eb66a685aa6d0b81c0cef1cf8bfe0b3c4 (rename(): fix the locking of subdirectories) which mentions NFS but doesn’t describe the potential impact. We’re running 5.15.148 now and as it’s been another 2 months there might be the chance of another lockup in the near future ;) If anyone has ideas on how to debug/approach a reproducer I’d be more than happy to help and try to provide more data.
