Description of problem:
Deleting a XFS file with lots of extents may cause a soft lockup if the
preemption model is none(CONFIG_PREEMPT_NONE=y or preempt=none is set
in the kernel cmdline). Alibaba cloud kernel and Oracle UEK container
kernel are affected by the issue, since they select CONFIG_PREEMPT_NONE=y.
