Subject: [PATCH 0/2] tracing: Fix snapshot accounting
Date: Thu, 22 Feb 2024 20:33:23 -0500 [thread overview]
Message-ID: <20240223013323.798805901@goodmis.org> (raw)
The ring buffer mapping test failed after running the ftrace tests.
This was due to some mismatched snapshot accounting that left the
snapshot counter enabled when it was not, which prevents the ring buffer
from being mapped.
Steven Rostedt (Google) (2):
tracing: Fix snapshot counter going between two tracers that use it
tracing: Decrement the snapshot if the snapshot trigger fails to register
