Sorry, please, explain what is racy.
reiserfs_truncate and reiserfs_release call that function after they have
inode's mutex locked.
Calling truncate inside i_size (ie. vmtruncate_range is also racy), because
of the way that the pagefault side of the equation works (eg. truncate_count).
But if you're only calling truncate on files that are never mmapped, then I
think that race should disappear.
