What we want is to have non-counting references to children in pagecache of parent directory, and avoid picking them after a child has been freed. Fine, so let's just have ->d_prune() clear parent's inode "has directory contents in page cache" flag. That way we don't need ->d_fsdata for storing offsets, so we can use it as a quick and dirty "is it referenced from page cache" flag. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
