PARPORT_EPP_FAST flag currently uses 32-bit I/O port access for data read/write (insl/outsl). Add PARPORT_EPP_FAST_16 and PARPORT_EPP_FAST_8 that use insw/outsw and insb/outsb (and PARPORT_EPP_FAST_32 as alias for PARPORT_EPP_FAST). Signed-off-by:

It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

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.
