accident, e.g.

foo "${i}" ## using 'i' with an unexpected value
done
After a quick look, it looks like 'i' is currently not used after having
been modified in __ksft_status_merge(), but still, better be safe than
sorry. I saw this while modifying the same file, not because I suspected

We've added 8 non-merge commits during the last 6 day(s) which contain
a total of 9 files changed, 34 insertions(+), 35 deletions(-).
The main changes are:
1) Fix a potential use-after-free in bpf_link_free when the link uses
dealloc_deferred to free the link object but later still tests for
presence of link->ops->dealloc, from Cong Wang.
2) Fix BPF test infra to set the run context for rawtp test_run callback
where syzbot reported a crash, from Jiri Olsa.
3) Fix bpf_session_cookie BTF_ID in the special_kfunc_set list to exclude
it for the case of !CONFIG_FPROBE, also from Jiri Olsa.
4) Fix a Coverity static analysis report to not close() a link_fd of -1
in the multi-uprobe feature detector, from Andrii Nakryiko.
5) Revert support for redirect to any xsk socket bound to the same umem
as it can result in corrupted ring state which can lead to a crash when
flushing rings. A different approach will be pursued for bpf-next to
address it safely, from Magnus Karlsson.
6) Fix inet_csk_accept prototype in test_sk_storage_tracing.c which caused
BPF CI failure after the last tree fast forwarding, from Andrii Nakryiko.
7) Fix a coccicheck warning in BPF devmap that iterator variable cannot
be NULL, from Thorsten Blum.

Let's test that we can have shared zeropages in our process as long as
storage keys are not getting used, that shared zeropages are properly
unshared (replaced by anonymous pages) once storage keys are enabled,
and that no new shared zeropages are populated after storage keys
were enabled.
We require the new pagemap interface to detect the shared zeropage.
On an old kernel (zeropages always disabled):
# ./s390x/shared_zeropage_test
TAP version 13

not ok 1 Shared zeropages should be enabled
ok 2 Shared zeropage should be gone

This warning fires because test_name is passed into asprintf(3), which
then changes it.
Fix this by simply removing the const qualifier. This is a local
automatic variable in a very short function, so there is not much need
to use the compiler to enforce const-ness at this scope.

It's slightly better to set _GNU_SOURCE in the source code, but if one
must do it via the compiler invocation, then the best way to do so is
this:
$(CC) -D_GNU_SOURCE=
...because otherwise, if this form is used:
$(CC) -D_GNU_SOURCE
...then that leads the compiler to set a value, as if you had passed in:
$(CC) -D_GNU_SOURCE=1
That, in turn, leads to warnings under both gcc and clang, like this:
futex_requeue_pi.c:20: warning: "_GNU_SOURCE" redefined
Fix this by using the "-D_GNU_SOURCE=" form.

Recent commit 0cfe71f45f ("netdev: add queue stats") added
a lot of useful stats, but only those immediately needed by virtio.
Presumably virtio does not support CHECKSUM_COMPLETE,
so statistic for that form of checksumming wasn't included.
Other drivers will definitely need it, in fact we expect it
to be needed in net-next soon (mlx5). So let's add the definition
of the counter for CHECKSUM_COMPLETE to uAPI in net already,
so that the counters are in a more natural order (all subsequent
counters have not been present in any released kernel, yet).

The kprobe_eventname.tc test checks if a function with .isra. can have a
kprobe attached to it. It loops through the kallsyms file for all the
functions that have the .isra. name, and checks if it exists in the
available_filter_functions file, and if it does, it uses it to attach a
kprobe to it.
The issue is that kprobes can not attach to functions that are listed more
than once in available_filter_functions. With the latest kernel, the
function that is found is: rapl_event_update.isra.0
# grep rapl_event_update.isra.0 /sys/kernel/tracing/available_filter_functions
rapl_event_update.isra.0
rapl_event_update.isra.0
It is listed twice. This causes the attached kprobe to it to fail which in
turn fails the test. Instead of just picking the function function that is
found in available_filter_functions, pick the first one that is listed
only once in available_filter_functions.
