2022-01-05ata: libata: remove pointless VPRINTK() callsHannes Reinecke
Most of the information is already covered by tracepoints (if not downright pointless), so remove the VPRINTK() calls. And while we're at it, remove ata_scsi_dump_cdb(), too, as this information can be retrieved from scsi tracing.

2022-01-04ata: libata: add reset tracepointsHannes Reinecke
To follow the flow of control we should be using tracepoints, as they will tie in with the actual I/O flow and deliver a better overview about what it happening. This patch adds tracepoints for hard reset, soft reset, and postreset and adds them in the libata-eh control flow. With that we can drop the reset DPRINTK calls in the various drivers.

2022-01-04ata: sata_fsl: Use struct_group() for memcpy() regionKees Cook
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Use struct_group() in struct command_desc around members acmd and fill, so they can be referenced together. This will allow memset(), memcpy(), and sizeof() to more easily reason about sizes, improve readability, and avoid future warnings about writing beyond the end of acmd: In function 'fortify_memset_chk', inlined from 'sata_fsl_qc_prep' at drivers/ata/sata_fsl.c:534:3: ./include/linux/fortify-string.h:199:4: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()?

SLsmg_reset_smg() resets the SLsmg screen management routines by freeing all memory allocated while it was active. However SLsmg_reinit_smg() maybe be called by another thread. SLsmg_reinit_smg() will free the same memory accessed by SLsmg_reset_smg(), thus it results in a double free. SLsmg_reinit_smg() is called already protected by ui__lock, so we fix the problem by adding pthread_mutex_trylock of ui__lock when calling SLsmg_reset_smg().

2022-01-02perf pmu: Fix alias events listJohn Garry
Commit 0e0ae8742207c3b4 ("perf list: Display hybrid PMU events with cpu type") changes the event list for uncore PMUs or arm64 heterogeneous CPU systems, such that duplicate aliases are incorrectly listed per PMU (which they should not be), like: # perf list ... unc_cbo_cache_lookup.any_es [Unit: uncore_cbox L3 Lookup any request that access cache and found line in E or S-state] unc_cbo_cache_lookup.any_es [Unit: uncore_cbox L3 Lookup any request that access cache and found line in E or S-state] unc_cbo_cache_lookup.any_i [Unit: uncore_cbox L3 Lookup any request that access cache and found line in I-state] unc_cbo_cache_lookup.any_i [Unit: uncore_cbox L3 Lookup any request that access cache and found line in I-state] ... Notice how the events are listed twice. The named commit changed how we remove duplicate events, in that events for different PMUs are not treated as duplicates. I suppose this is to handle how "Each hybrid pmu event has been assigned with a pmu name". Fix PMU alias listing by restoring behaviour to remove duplicates for non-hybrid PMUs.
