Hi Christian,

Kernel testing reported regression bugs in this patch series:
-  Reported-by: kernel test robot <lkp at intel.com>
    Closes: 
202507142128.Zr5StnYh-lkp at intel.com/">https://lore.kernel.org/oe-kbuild-all/202507142128.Zr5StnYh-lkp@intel.com/

- Reported-by: kernel test robot <lkp at intel.com>
   Closes: 
202507142040.wppyoX1s-lkp at intel.com/">https://lore.kernel.org/oe-kbuild-all/202507142040.wppyoX1s-lkp@intel.com/

I will send an updated version of the patch series shortly to address 
these issues.
Please consider dropping the original series from the vfs-6.17.misc 
branch once the new version is reviewed.

Thanks, and sorry for the trouble.
