lttng-ust maintains a branch per minor series (stable-2.13 through
stable-2.16) and releases from several at once: 2.14.2 and 2.15.1 went out
the same day in May 2026, and three series together in February, 2.13.10,
2.14.1 and 2.15.0. So upgrades within a major.minor are stable point
upgrades per the OE-Core stable release policy (ref-manual, "Stable Point
Release Upgrades"). There is no written policy document, so qualification
rests on that branch structure and the release contents below.

  https://docs.yoctoproject.org/dev/ref-manual/release-process.html#stable-point-release-upgrades
  https://github.com/lttng/lttng-ust/tree/stable-2.15

Upstream keeps a ChangeLog with a per-release entry list, and every entry
for the one point release in the current series is labelled a fix. 2.15.1
(May 22 2026) covers a negative error code on incorrect message size, a
shmp() return value checked before dereference, an underflow warning in
zero_file, uninitialised LTTNG_UST_LFILE and sigevent structs, close_range
inefficiency and excessive fd-tracker memory use, and a NULL check in
ustctl. The one non-fix entry changes a likely to unlikely branch hint.

Only one point release exists in the 2.15 series so far, so this also
rests on the 2.13 series' record, which ran to ten.

Already tracked this way on the OE stable branches, counting only bumps
since each branch forked: kirkstone took 2.13.5 -> 2.13.6 and scarthgap
2.13.7 -> 2.13.8 -> 2.13.10. wrynose has taken none and sits at 2.14.0.
