From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Shuo Liu Date: Sat, 29 Sep 2018 11:00:46 +0800 Subject: [PATCH] vhm: change trace_printk of vhm_dev_ioctl to pr_debug trace_printk will write into the ring buffer by default. Actually, we don't need this trace entry as there are many vhm ioctls happen at runtime which will flood the ring buffer. So change it to dynamic printk.
