Subject: [RELEASE] LTTng-modules 2.14.6 and 2.15.2 (Linux kernel tracer)
Date: Fri, 19 Jun 2026 14:56:17 -0400 [thread overview]
Message-ID: <394956c8-9e78-456b-845d-54a3219214d4@efficios.com> (raw)
This is a stable release announcement for the LTTng kernel tracer,
an out-of-tree kernel tracer for the Linux kernel.
The LTTng project provides low-overhead, correlated userspace and
kernel tracing on Linux. Its use of the Common Trace Format and a
flexible control interface allows it to fulfill various workloads.
The most relevant changes in these releases introduce support for version
7.1 of the Linux kernel.

* fix: leaked file and fd on channel create error
* fix: backport: hrtimer: Reduce trace noise in hrtimer_start() (v6.1.175)
* fix: ext4: widen trace event i_ino fields to u64 (v7.1)
* fix: ext4: delete some unused tracepoint definitions (v5.13)
* fix: ext4: enhance tracepoints during the folios writeback (v6.17)
* fix: btrfs: tracepoints, use correct type for inode number (v4.18)
