Subject: Re: [PATCH net-next] net: add a route cache full diagnostic message

From: Peter Oskolkov <>
Date: Wed, 16 Jan 2019 08:50:28 -0800

> In some testing scenarios, dst/route cache can fill up so quickly
> that even an explicit GC call occasionally fails to clean it up. This leads
> to sporadically failing calls to dst_alloc and "network unreachable" errors
> to the user, which is confusing.
> This patch adds a diagnostic message to make the cause of the failure
> easier to determine.
