You can overcome this by using -d (default) option, this allows us to set an acl rule to be the default rule. When this is set on a directory then all new files or directories created within that directory inherit the same acl rules.
It is just like chmod -R ( not same as )
#setfacl -dm u:xxxxxxxxxx:rw /directory
by using the above command you can give the r,w permission to all newly created files or auto generated files in /directory.
