From 0d8a374673c9bc62bc78a2d8fe64553a51542cb4 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 1 Aug 2010 20:14:55 -0400 Subject: SUNRPC: Defer deleting the security context until gss_do_free_ctx() There is no need to delete the gss context separately from the rest of the security context information, and doing so gives rise to a an rcu_dereference_check() warning.
