Pity userspace on where this is done on a simple minded filesystemPity userspace on where this is done on a simple minded filesystemPosted May 6, 2009 18:49 UTC (Wed) by jzbiciak (✭ supporter ✭, #5246)In reply to: Pity userspace on where this is done on a simple minded filesystem by adj Parent article: The two sides of reflink()
Simple answer: Don't implement this on simple minded filesystems. :-) Save it for filesystems that COW effectively (Btrfs), or can be taught to do so (ext4). I doubt anyone's planning to implement this over xiafs or vfat.
Slightly fancier answer: Perhaps this is another thing to "ulimit"? Return EPERM or EFBIG (file is too big) if the limit's exceeded.
