Subject: [for-next][PATCH 07/16] tracing: Increase tracing map KEYS_MAX size
Date: Fri, 06 Oct 2017 14:07:02 -0400 [thread overview]
Message-ID: <20171006180729.273538657@goodmis.org> (raw)
In-Reply-To: <20171006180655.935479946@goodmis.org>
[-- Attachment #1: 0007-tracing-Increase-tracing-map-KEYS_MAX-size.patch --]
[-- Type: text/plain, Size: 970 bytes --]
From: Tom Zanussi <tom.zanussi@linux.intel.com>
The current default for the number of subkeys in a compound key is 2,
which is too restrictive. Increase it to a more realistic value of 3.
