Subject: 	Add debugging to better detect negotiation of enctype not supported by kernel
X-Git-Tag: nfs-utils-1-0-8~12
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=7c0658702830ca9f4d019bbdca0d94fa657a0f17;hp=05424b57b5ccfefcfee415f97d5c4063d2ab314e

	Add debugging to better detect negotiation of enctype not supported by kernel

	Print debugging message indicating the type of encryption keys being sent
	down to the kernel.  This should make it easier to detect cases where
	unsupported encryption types are being negotiated.
	(really this time)
