From f8e68a7c9af5f8047f7f8295874bedf306063709 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Thu, 11 Feb 2016 13:05:47 -0700 Subject: NVMe: Rate limit nvme IO warnings We don't need to spam the kernel logs with thousands of IO cancelling messages. We can infer all IO's are being cancelled with fewer, or even none at all. This patch rate limits the message and uses the debug log level as it is mainly used for testing purposes.
