[PATCH v2] perf probe: Fix to delete multiple probe event

by Masami Hiramatsu

Fix to delete multiple probe event with filter correctly. When we put an event with multiple probes, perf-probe fails to delete with filters. This comes from a failure to list up the event name because of overwrapping its name. To fix this issue, skip to list up the event which has same name. Without this patch: # perf probe -l \* probe_perf:map__map_ip (on perf_sample__fprintf_brstackoff:21@ probe_perf:map__map_ip (on perf_sample__fprintf_brstackoff:25@ probe_perf:map__map_ip (on append_inlines:12@util/machine.c in probe_perf:map__map_ip (on unwind_entry:19@util/machine.c in / probe_perf:map__map_ip (on map__map_ip(a)util/map.h in /home/mhi probe_perf:map__map_ip (on map__map_ip(a)util/map.h in /home/mhi # perf probe -d \* "*" does not hit any event.

I noticed this patch is in mainline now as: ce57785bf91b net: qrtr: fix len of skb_put_padto in qrtr_node_enqueue Though I'm not an expert on the code, it feels like a stable candidate unless someone objects. -Doug

[PATCH v4 1/3] x86/tsc_msr: Use named struct initializers

Use named struct initializers for the freq_desc struct-s initialization and change the "u8 msr_plat" to a "bool use_msr_plat" to make its meaning more clear instead of relying on a comment to explain it.

[PATCH] powerpc/fsl_booke: avoid creating duplicate tlb1 entry

by Laurentiu Tudor

In the current implementation, the call to loadcam_multi() is wrapped between switch_to_as1() and restore_to_as0() calls so, when it tries to create its own temporary AS=1 TLB1 entry, it ends up duplicating the existing one created by switch_to_as1(). Add a check to skip creating the temporary entry if already running in AS=1.

[PATCH 1/8] xarray: Fix premature termination of xas_for_each_marked()

by Jan Kara

xas_for_each_marked() is using entry == NULL as a termination condition of the iteration. When xas_for_each_marked() is used protected only by RCU, this can however race with xas_store(xas, NULL) in the following way: TASK1 TASK2 page_cache_delete() find_get_pages_range_tag() xas_for_each_marked() xas_find_marked() off = xas_find_chunk() xas_store(&xas, NULL) xas_init_marks(&xas); ... rcu_assign_pointer(*slot, NULL); entry = xa_entry(off); And thus xas_for_each_marked() terminates prematurely possibly leading to missed entries in the iteration (translating to missing writeback of some pages or a similar problem). Fix the problem by creating a special version of xas_find_marked() - xas_find_valid_marked() - that does not return NULL marked entries and changing xas_next_marked() in the same way.
