There is no external users of slab_start/next/stop(), so make them static. And the memory.kmem.slabinfo is deprecated, which outputs nothing now, so move memcg_slab_show() into mm/memcontrol.c and rename it to mem_cgroup_slab_show to be consistent with other function names.

Calling kmem_cache_destroy() while the cache still has objects allocated is a kernel bug, and will usually result in the entire cache being leaked. While the message in kmem_cache_destroy() resembles a warning, it is currently not implemented using a real WARN(). This is problematic for infrastructure testing the kernel, all of which rely on the specific format of WARN()s to pick up on bugs. Some 13 years ago this used to be a simple WARN_ON() in slub, but commit d629d819 ("slub: improve kmem_cache_destroy() error message") changed it into an open-coded warning to avoid confusion with a bug in slub itself. Instead, turn the open-coded warning into a real WARN() with the message preserved, so that test systems can actually identify these issues, and we get all the other benefits of using a normal WARN(). The warning message is extended with "when called from <caller-ip>" to make it even clearer where the fault lies. For most configurations this is only a cosmetic change, however, note that WARN() here will now also respect panic_on_warn.

__user annotations are used by the checker (e.g sparse) to mark user pointers. However here __user is applied to a struct directly, without a pointer being directly involved. Although the presence of __user does not cause sparse to emit a warning, __user should be removed for consistency with other uses of offsetof(). Note: No functional changes intended.

Since irq request is the last thing in the driver probe, it happens later than the input device registration. This means that there is a small time window where if the open method is called the driver will attempt to enable not yet available irq. Fix that by moving the irq request before the input device registration. Reviewed-by:

This largely reverts commit 5a7b95fb. It breaks suspend with AMD GPUs, and we couldn't incrementally fix it. So, let's remove the code and go back to the drawing board. We keep the header extension to not break drivers already populating the regulator. We expect to re-add the code handling it soon.

This reverts commit 08efcb4a . This breaks the build as it will prefer using libbpf-devel header files, even when not using LIBBPF_DYNAMIC=1, breaking the build. This was detected on OpenSuSE Tumbleweed with libtraceevent-devel 1.3.0, as described by Jiri Slaby: ======================================================================= It breaks build with LIBTRACEEVENT_DYNAMIC and version 1.3.0: > util/debug.c: In function ‘perf_debug_option’: > util/debug.c:243:17: error: implicit declaration of function ‘tep_set_loglevel’ [-Werror=implicit-function-declaration] > 243 | tep_set_loglevel(TEP_LOG_INFO); > | ^~~~~~~~~~~~~~~~ > util/debug.c:243:34: error: ‘TEP_LOG_INFO’ undeclared (first use in this function); did you mean ‘TEP_PRINT_INFO’? > 243 | tep_set_loglevel(TEP_LOG_INFO); > | ^~~~~~~~~~~~ > | TEP_PRINT_INFO > util/debug.c:243:34: note: each undeclared identifier is reported only once for each function it appears in > util/debug.c:245:34: error: ‘TEP_LOG_DEBUG’ undeclared (first use in this function) > 245 | tep_set_loglevel(TEP_LOG_DEBUG); > | ^~~~~~~~~~~~~ > util/debug.c:247:34: error: ‘TEP_LOG_ALL’ undeclared (first use in this function) > 247 | tep_set_loglevel(TEP_LOG_ALL); > | ^~~~~~~~~~~ It is because the gcc's command line looks like: gcc ... -I/home/abuild/rpmbuild/BUILD/tools/lib/ ... -DLIBTRACEEVENT_VERSION=65790 ... ======================================================================= The proper way to fix this is more involved and so not suitable for this late in the 5.16-rc stage.

When running 'perf trace' with an BPF object like: # perf trace -e openat,tools/perf/examples/bpf/hello.c the event parsing eventually calls llvm__get_kbuild_opts() that runs a script and that ends up with SIGCHLD delivered to the 'perf trace' handler, which assumes the workload process is done and quits 'perf trace'. Move the SIGCHLD handler setup directly to trace__run(), where the event is parsed and the object is already compiled. Signed-off-by:
