From d8558f99fbc5ef5d4ae76b893784005056450f82 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 10 Jul 2007 15:19:26 -0400 Subject: sunrpc: drop BKL around wrap and unwrap We don't need the BKL when wrapping and unwrapping; and experiments by Avishay Traeger have found that permitting multiple encryption and decryption operations to proceed in parallel can provide significant performance improvements.
