From c17a7c6ee8177e0da998784c06f37fc093507c5b Mon Sep 17 00:00:00 2001 From: Thomas Richter Date: Fri, 22 Nov 2019 13:42:55 +0100 Subject: [PATCH] s390/cpum_sf: Remove unnecessary check for pending SDBs In interrupt handling the function extend_sampling_buffer() is called after checking for a possibly extension. This check is not necessary as the called function itself performs this check again.
