Subject: [PATCH 10/18 v3] x86/tlb/trace: Export enums in used by tlb_flush tracepoint
Date: Thu, 02 Apr 2015 21:38:12 -0400 [thread overview]
Message-ID: <20150403014124.461724255@goodmis.org> (raw)
In-Reply-To: 20150403013802.220157513@goodmis.org
[-- Attachment #1: 0010-x86-tlb-trace-Export-enums-in-used-by-tlb_flush-trac.patch --]
[-- Type: text/plain, Size: 1645 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
Have the enums used in __print_symbolic() by the trace_tlb_flush()
tracepoint exported to userpace such that they can be parsed by
userspace tools.
