Maybe, OTOH e.g. ACLs (dynamic size) are implemented by storing them as xattrs
on 9p server as well, and this change somewhat expects server to run Linux as
well. So maybe s/XATTR_SIZE_MAX/KMALLOC_MAX_SIZE/ might be more appropriate,
considering that this patch is about fixing a potential kmalloc() warning?

Worth to mention in the commit log BTW what the issue was.
