CONFIG_EFI_VARS_PSTORE 有人了解这个东西么

今天编译新内核增加了一个选择项，一时没找到详细的说明。

We know that with some firmware implementations writing too much data to
UEFI variables can lead to bricking machines. Recent changes attempt to
address this issue, but for some it may still be prudent to avoid
writing large amounts of data until the solution has been proven on a
wide variety of hardware.

Crash dumps or other data from pstore can potentially be a large data
source. Add a new option, CONFIG_EFI_VARS_PSTORE, which can be set to N
to avoid using efivars as a backend to pstore.

简单的说,和efi的安全性有关的一个选项,保持默认即可.
