The Freescale QorIQ AHCI SATA controller is only present on Freescale Layerscape SoCs. Add platform dependencies to the AHCI_QORIQ config symbol, to avoid asking the user about it when configuring a kernel without Layerscape support. Signed-off-by:

Pull tracing fixes from Steven Rostedt: - Fix setting affinity of hwlat threads in containers Using sched_set_affinity() has unwanted side effects when being called within a container. Use set_cpus_allowed_ptr() instead - Fix per cpu thread management of the hwlat tracer: - Do not start per_cpu threads if one is already running for the CPU - When starting per_cpu threads, do not clear the kthread variable as it may already be set to running per cpu threads - Fix return value for test_gen_kprobe_cmd() On error the return value was overwritten by being set to the result of the call from kprobe_event_delete(), which would likely succeed, and thus have the function return success - Fix splice() reads from the trace file that was broken by commit 36e2c742 ("fs: don't allow splice read/write without explicit ops") - Remove obsolete and confusing comment in ring_buffer.c The original design of the ring buffer used struct page flags for tricks to optimize, which was shortly removed due to them being tricks. But a comment for those tricks remained - Set local functions and variables to static * tag 'trace-v6.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/hwlat: Replace sched_setaffinity with set_cpus_allowed_ptr ring-buffer: remove obsolete comment for free_buffer_page() tracing: Make splice_read available again ftrace: Set direct_ops storage-class-specifier to static trace/hwlat: Do not start per-cpu thread if it is already running trace/hwlat: Do not wipe the contents of per-cpu thread data tracing/osnoise: set several trace_osnoise.c variables storage-class-specifier to static tracing: Fix wrong return in kprobe_event_gen_test.c -

There is a problem with the behavior of hwlat in a container, resulting in incorrect output. A warning message is generated: "cpumask changed while in round-robin mode, switching to mode none", and the tracing_cpumask is ignored. This issue arises because the kernel thread, hwlatd, is not a part of the container, and the function sched_setaffinity is unable to locate it using its PID. Additionally, the task_struct of hwlatd is already known. Ultimately, the function set_cpus_allowed_ptr achieves the same outcome as sched_setaffinity, but employs task_struct instead of PID. Test case: # cd /sys/kernel/tracing # echo 0 > tracing_on # echo round-robin > hwlat_detector/mode # echo hwlat > current_tracer # unshare --fork --pid bash -c 'echo 1 > tracing_on' # dmesg -c Actual behavior: [573502.809060] hwlat_detector: cpumask changed while in round-robin mode, switching to mode none Link: https://lore.kernel.org/linux-trace-kernel/20230316144535.1004952-1-costa.shul@redhat.com Cc: Masami Hiramatsu <mhiramat@kernel.org> Fixes: 0330f7aa ("tracing: Have hwlat trace migrate across tracing_cpumask CPUs") Signed-off-by:

The comment refers to mm/slob.c which is being removed. It comes from commit ed56829c ("ring_buffer: reset buffer page when freeing") and according to Steven the borrowed code was a page mapcount and mapping reset, which was later removed by commit e4c2ce82 ("ring_buffer: allocate buffer page pointer"). Thus the comment is not accurate anyway, remove it.

Since the commit 36e2c742 ("fs: don't allow splice read/write without explicit ops") is applied to the kernel, splice() and sendfile() calls on the trace file (/sys/kernel/debug/tracing /trace) return EINVAL. This patch restores these system calls by initializing splice_read in file_operations of the trace file. This patch only enables such functionalities for the read case.

In order to not jeopardize the sanity of everyone involved in maintaining this code, the request issuing side has received a cleanup, split in more or less trivial, small and digestible pieces.

The hwlatd tracer will end up starting multiple per-cpu threads with the following script: #!/bin/sh cd /sys/kernel/debug/tracing echo 0 > tracing_on echo hwlat > current_tracer echo per-cpu > hwlat_detector/mode echo 100000 > hwlat_detector/width echo 200000 > hwlat_detector/window echo 1 > tracing_on To fix the issue, check if the hwlatd thread for the cpu is already running, before starting a new one. Along with the previous patch, this avoids running multiple instances of the same CPU thread on the system.

Overwriting the error code with the deletion result may cause the function to return 0 despite encountering an error. Commit b111545d ("tracing: Remove the useless value assignment in test_create_synth_event()") solves a similar issue by returning the original error code, so this patch does the same.
