[ fs list of truncate fun ]
Thanks, it should be useable on reiserfs, and I'm neck deep in
reiserfs_truncate right now anyway. The packed files don't care about
this at all, they get read into a zero'd page for readpage, or unpacked
for writing. The unpacked tails will need a similar change to the one in
ext2.

test1 had rare file data corruption, test2 was not at all pretty. The
tools aren't there to test VFS, or even the correctness of a given file
op (those tests are done by hand when we make changes). There are two
common mistakes that we (reiserfs coders) make: missing a brelse, and not
dealing properly with a schedule. The load scripts are very good at
finding those.
