Subject: SUNRPC: Ensure to ratelimit the "server not responding" syslog messages
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=0729d995f2a2726598642d552ebe916b43aef73d;p=android-x86%2Fkernel.git

SUNRPC: Ensure to ratelimit the "server not responding" syslog messages

In particular, the timeout messages can be very noisy, so we ought to
ratelimit them in order to avoid spamming the syslog.
