From 83f619f3c8abb82cac9158cf23c656ec5c184607 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Wed, 7 Jul 2010 15:32:02 +0200 Subject: padata: make padata_do_parallel to return zero on success To return -EINPROGRESS on success in padata_do_parallel was considered to be odd. This patch changes this to return zero on success. Also the only user of padata, pcrypt is adapted to convert a return of zero to -EINPROGRESS within the crypto layer. This also removes the pcrypt fallback if padata_do_parallel was called on a not running padata instance as we can't handle it anymore. This fallback was unused, so it's save to remove it.
