Subject: SUNRPC: Add support for privacy to generic gss-api code.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=293f1eb551a77fe5c8956a559a3c0baea95cd9bc;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

SUNRPC: Add support for privacy to generic gss-api code.

 Add support for privacy to generic gss-api code.  This is dead code until we
 have both a mechanism that supports privacy and code in the client or server
 that uses it.
