如何更改/dev/hugepages的权限?

我有一个应用程序可以打开()下面的文件/dev/hugepages来分配一个大页面。目前,它需要 root。

我如何更改权限?

它由 F38 自动安装:

#/usr/lib/systemd/system/dev-hugepages.mount

[Unit]

DefaultDependencies=no
Before=sysinit.target
ConditionPathExists=/sys/kernel/mm/hugepages
ConditionCapability=CAP_SYS_ADMIN
ConditionVirtualization=!private-users

[Mount]
What=hugetlbfs
Where=/dev/hugepages
Type=hugetlbfs

我尝试在 [Mount] 下添加这一行:

Options=uid=1000

运气不好的话,权限是正确使用的ls,但它就是不起作用。
