    [PATCH] vfs: add lock owner argument to flush operation · 75e1fcc0
    Miklos Szeredi authored
    Pass the POSIX lock owner ID to the flush operation.
    This is useful for filesystems which don't want to store any locking state
    in inode->i_flock but want to handle locking/unlocking POSIX locks
    internally.  FUSE is one such filesystem but I think it possible that some
    network filesystems would need this also.
    Also add a flag to indicate that a POSIX locking request was generated by
    close(), so filesystems using the above feature won't send an extra locking
    request in this case.
