error in compiling openafs-1.8.9 on Rocky 9.1

I get errors in compiling the kernel module of openafs 1.8.9 on Rocky 
9.1 x86_64

This is what the compilation returns:

> /root/openafs-1.8.9/openafs-1.8.9/src/libafs/MODLOAD-5.14.0-162.6.1.el9_1.0.1.x86_64-MP/osi_vnodeops.c:3617:25: error: ‘block_dirty_folio’ undeclared here (not in a function); did you mean ‘swap_dirty_folio’?
