More OT: dmesg says
Checking ReiserFS transaction log (device ...
Using r5 hash to sort names
It tells me r5 whenever a filesystem gets mounted so it is r5. The point
is that XFS is known to be weak when deleting files but in my test
ReiserFS was even slower.
Weird, better tell them on the reiserfs list what is happening with detail
which will help them.
Every program has two purposes one for which

I use the last kind.
