Doc Text:	.System works correctly without the soft lockup while starting a VDO volume Due to fixing a Kernel Application Binary Interface (kABI) bug in the `pv_mmu_ops` structure, RHEL 8.7 systems with kernel version `4.18.0-425.10.1.el8_7`, that is RHEL-8.7.0.2-BaseOS, hung or encountered a kernel panic due to soft lockup while starting a Virtual Data Optimizer (VDO) volume. With this update, the `kmod-kvdo` package was rebuilt any time a new kernel was available that is no longer kABI compatible with the current version of `kmod-kvdo`. As a result, the system works correctly while starting a VDO volume.	Story Points:	---
