Subject: [for-linus][PATCH 0/7] tracing: Fixes for 5.14-rc2
Date: Fri, 23 Jul 2021 08:54:54 -0400	[thread overview]
Message-ID: <20210723125454.570472450@goodmis.org> (raw)


- Fix deadloop in ring buffer because of using stale "read" variable

- Fix synthetic event use of field_pos as boolean and not an index

- Fixed histogram special var "cpu" overriding event fields called "cpu"

- Cleaned up error prone logic in alloc_synth_event()

- Removed call to synchronize_rcu_tasks_rude() when not needed

- Removed redundant initialization of a local variable "ret"

- Fixed kernel crash when updating tracepoint callbacks of different
  priorities.


Colin Ian King (1):
      ftrace: Remove redundant initialization of variable ret

Haoran Luo (1):
      tracing: Fix bug in rb_per_cpu_empty() that might cause deadloop.

Nicolas Saenz Julienne (1):
      ftrace: Avoid synchronize_rcu_tasks_rude() call when not necessary

Steven Rostedt (VMware) (4):
      tracing: Synthetic event field_pos is an index not a boolean
      tracing/histogram: Rename "cpu" to "common_cpu"
      tracing: Clean up alloc_synth_event()
      tracepoints: Update static_call before tp_funcs when adding a tracepoint
