From: Keith Busch Date: Thu, 11 Feb 2016 20:05:47 +0000 (-0700) Subject: NVMe: Rate limit nvme IO warnings X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f8e68a7c9af5f8047f7f8295874bedf306063709;p=linux.git 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.
