From f3680312a737355ddf35c1b68af25e384d7ef0a8 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 13 Oct 2005 16:54:48 -0400 Subject: [PATCH] SUNRPC: Retry wrap in case of memory allocation failure. For privacy we need to allocate extra pages to hold encrypted page data when wrapping requests. This allocation may fail, and we handle that case by waiting and retrying. Signed-off-by: J.
