Subject: reiserfs-truncate-blocks-not-used-by-a-write-v2-fix
From: Jan Kara <jack@xxxxxxx>
Andrew, this patch should have been replaced by the one below - this
version causes data corruption when using writev() (same problem as ext3 &
ext4 had)... I've sent you a new version on 2009-12-02 but apparently you
didn't see it.
