Hello,

I have been testing these patches and do not see the xattr information when
trying to retrieve it within the initramfs, do you have an example of how
you tested this originally?

Hi Jim, all

apologies, I didn't find yet the time to look at this.

Hello Roberto,

Thank you for your response, I can wait until you have looked at the patches,
I asked the question to make sure it was not something wrong in my
configuration.

Uhm, I guess this could be solved with:

https://github.com/openeuler-

mirror/kernel/commit/18a502f7e3b1de7b9ba0c70896ce08ee13d052da

and adding initramtmpfs to the kernel command line. You are
probably using ramfs, which does not have xattr support.

Can I clarify which filesystem type is supported with this patch series?
Is it tmpfs or perhaps a ramdisk?

Thank you, I have tested that patch but the problem remained. Here is my
command line, I wonder if there is something wrong.

Kernel command line: rw rootfstype=initramtmpfs root=/dev/ram0
initrd=0x500000000 rootwait

It is just initramtmpfs, without rootfstype=.

Roberto

Best regards,
Jim
