Subject: [RELEASE] LTTng-modules 2.13.22 and 2.14.3 (Linux kernel tracer)

Hi,

This is a stable release announcement for the LTTng kernel tracer,
an out-of-tree kernel tracer for the Linux kernel.

The main change included in both 2.13.22 and 2.14.3 releases is a fix for the
get_pfnblock_flags_mask / get_pfnblock_migratetype wrappers for v6.17.

It adds a version gate for the get_pfnblock_flags_mask wrapper as the
symbol was removed in v6.17 and thus initialization would always fail
preventing the modules load.

The fix of CTF version in metadata packet headers for CTF2 should not
have observable effects for end users, it's mostly for consistency.

* Changelog:

2025-10-17 LTTng modules 2.13.22
         * fix: always print to kernel log on module load failure
         * fix: get_pfnblock_flags_mask / get_pfnblock_migratetype wrappers for v6.17

2025-10-17 LTTng modules 2.14.3
         * Fix: Set CTF version in metadata packet headers for CTF2
         * fix: always print to kernel log on module load failure
         * fix: get_pfnblock_flags_mask / get_pfnblock_migratetype wrappers for v6.17
         * fix: remove duplicated MODULE macros

Thanks,

Mathieu
