Subject: [REGRESSION 6.0.x / 6.1.x] NULL dereferencing at tracing
Date: Mon, 31 Oct 2022 08:11:28 +0100 [thread overview]
Message-ID: <87h6zklb6n.wl-tiwai@suse.de> (raw)
Hi Steven,
we've got a bug report indicating the NULL dereference at the recent
tracing changes, showing at the start of KDE. The details including
the dmesg are found at:
https://bugzilla.opensuse.org/show_bug.cgi?id=1204705
It was reported at first for 6.0.3, and confirmed that the problem
persists with 6.1-rc, too.
The culprit seems to be the commit
f3ddb74ad0790030c9592229fb14d8c451f4e9a8
tracing: Wake up ring buffer waiters on closing of the file
and reverting it seems fixing the problem.
Could you take a look?
thanks,
Takashi
