s390/zcrypt: ap bus rescan problem when toggle crypto adapters on/off The bus rescan process was called simultaneously on every device failure. This finally leads into race conditions (double device add/remove actions). This patch protects the rescan area by mutual exclusion and improves ap_config_timer handling Signed-off-by: Ingo Tuchscherer <ingo.tuchscherer@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
