Hi Linus,

This fixes a late breaking regression introduced in the v6.10 cycle and

Alex

VFIO fix for v6.10

 - Recent stable backports are exposing a bug introduced in the v6.10
   development cycle where a counter value is uninitialized.  This leads
   to regressions in userspace drivers like QEMU where where the kernel
   might ask for an arbitrary buffer size or return out of memory itself
   based on a bogus value.  Zero initialize the counter.  (Yi Liu)
