From d39aae9ec447dda84d9a2850743a78a535a71c90 Mon Sep 17 00:00:00 2001

Subject: add missing setattr methods

For the new truncate sequence every filesystem that wants to truncate on-disk
state needs a seattr method.  Convert the remaining filesystems that implement
the truncate inode operation to have its own setattr method.
