Union mounts is Hmm, anyone who meets crash in aufs, please let me know. While I never say aufs is bug-free, I don't receive such report recently. I always try fixing a bug as soon as possible when I got a report. A reply I have to write repeatedly to who have met a problem in aufs and reported to aufs-users ML, is "your aufs version is too old. please get the latest one." Because aufs is released every week and some linux distributions keep using very old aufs version, even over one year old version than thier release date. By the way, I don't have objection to merge Val's UnionMount into mainline as I have heard it is already decided. > But frankly, this is an impossible problem to solve generically at the > file system level. When a user says, "Show the changes to the lower > file system in my overlaid file system," they are actually saying, Is it (mostly) possible by receiving a notification via fsnotify? For remote FS, their ->d_revalidate() will tell us something is changed. J. R.
