Hum, weird. I have hard time understanding how that change could be causing fs corruption on Aplha but OTOH it is not completely unthinkable. With this commit we may migrate some block device pages we were not able to migrate previously and that could be causing some unexpected issue. I'll look into this.
To make things more interesting, it does not happen on any alpha but only one subarch so far: https://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg1889207.html is my original bug report. -- Meelis Roos <mroos@xxxxxxxx>
