From 4e5b0ad5827163bd8e57ea595be2681cad12e5c2 Mon Sep 17 00:00:00 2001 From: Gilad Ben-Yossef Date: Wed, 18 Oct 2017 08:00:36 +0100 Subject: crypto: remove redundant backlog checks on EBUSY Now that -EBUSY return code only indicates backlog queueing we can safely remove the now redundant check for the CRYPTO_TFM_REQ_MAY_BACKLOG flag when -EBUSY is returned.
