-------------------------------------------

Thanks Andrew for filing this JIRA. Me,  Alejandro, Yi discussed about this 
listing API initially when we defining APIs. That time we felt get api is 
enough for immediate needs and if there is a interest in listXattrs we can do. 

+1 on having separate API, and I don't see this can be blocker for merge

> Listing extended attributes with the search permission

> From the attr(5) manpage:
> {noformat}
>        Users with search access to a file or directory may retrieve a list  of
>        attribute names defined for that file or directory.
> {noformat}
> This is like doing {{getfattr}} without the {{-d}} flag, which we currently 
> don't support.
