The list is not wrong. I was just noting that it was too short, missing three items of particular interest for server filesystems (which seems to be the target environment). Support for: Directory change notification (F_NOTIFY) Distributed Caching (F_SETLEASE/F_GETLEASE/break_lease) POSIX ACLs The lack of support for lsattr/chattr (chflags) is less important, and the lack of support for the multipage operations (writepages and readpages) is not a compatability issue and is not critical, although it might hurt performance. I did see that you have aio - and that was interesting because there are so few implementations and that as well as vectorio was something I wanted to explore for the cifs vfs client.
