- /* posix xlator as part of listxattr will send both names
- * and values of the xattrs in the dict. But as per man page
- * listxattr is mainly supposed to send names of the all the
- * xattrs. gfapi, as of now will put all the keys it obtained
- * in the dict (sent by posix) into a buffer provided by the
- * caller (thus the values of those xattrs are lost). If some
- * xlator makes gfapi based calls (ex: snapview-server), then
- * it has to unwind the calls by putting those names it got
- * in the buffer again into the dict. But now it would not be
- * having the values for those xattrs. So it might just put
- * a 0 byte value ("") into the dict for each xattr and unwind
- * the call. So the xlators which cache the xattrs (as of now
- * md-cache caches the acl and selinux related xattrs), should
- * not update their cache if the value of a xattr is a 0 byte
- * data (i.e. "").
