stable inclusion from linux-4.19.147 commit 61279a7b3e337b8c8605987591964db4a2b3eb91
--------------------------------
[ Upstream commit 8c6b6c793ed32b8f9770ebcdf1ba99af423c303b ]
Since p points at raw xdr data, there's no guarantee that it's NULL terminated, so we should give a length. And probably escape any special characters too.
