Christian, This is a followup fix to the reported regression [1] that was introduced by overlayfs non-decodable file handles support in v6.6. The first fix posted two weeks ago [2] was a quick band aid which is justified on its own and is still queued on your vfs.fixes branch. This followup fix fixes the root cause of overlayfs file handle encoding failure and it also solves a bug with fanotify FAN_DELETE_SELF events on overlayfs, that was discovered from analysis of the first report. The fix to fanotify delete events was verified with a new LTP test [3]. Thanks, Amir.
