Re: [RFC PATCH v2 7/9] ksmbd: support security.xfstests EAs

This is how the current version works, but I believe there is an issue 
with it. Three days ago, I sent a private email to you and Steve 
outlining my proposal for improvement, which leverages the SMB3 POSIX 
extensions to implement this feature. However, your email system blocks 
messages from me, so I was unable to forward the email to you successfully.
