---------------------------------------
Hi Yi,
I thought we had standardized on "XAttr" as opposed to XATTR or xattr. It
doesn't matter to me which one we use, but I do want us to be consistent. In
the code we've been using XAttr as a general rule, modulo any specific
camel-casing that needs to be done.
> Copy command with preserve option should handle Xattrs

> The design docs for Xattrs stated that we handle preserve options with copy
> commands
> From doc:
> Preserve option of commands like “cp -p” shell command and “distcp -p” should
> work on XAttrs.
> In the case of source fs supports XAttrs but target fs does not support,
> XAttrs will be ignored
> with warning message
