Subject: [PATCH 0/2] module: Correctly truncate sysfs sections output

Hi,

This fixes my sysfs module sections refactoring to take into account
the case where the output buffer is not PAGE_SIZE. :( Thanks to 0day
and trinity for noticing.

I'll let this sit in -next for a few days and then send it to Linus.

-Kees
