      tracing/kprobes: Use rcu_dereference_raw for tp->files · c02c7e65
      Masami Hiramatsu 提交于
      Use rcu_dereference_raw() for accessing tp->files. Because the
      write-side uses rcu_assign_pointer() for memory barrier,
      the read-side also has to use rcu_dereference_raw() with
      read memory barrier.

      tracing: Fix leaks of filter preds · 60705c89
      Steven Rostedt (Red Hat) 提交于
      Special preds are created when folding a series of preds that
      can be done in serial. These are allocated in an ops field of
      the pred structure. But they were never freed, causing memory
      leaks.
      
      This was discovered using the kmemleak checker:
      
      unreferenced object 0xffff8800797fd5e0 (size 32):
        comm "swapper/0", pid 1, jiffies 4294690605 (age 104.608s)

       "The majority of these changes are from Masami Hiramatsu bringing
        kprobes up to par with the latest changes to ftrace (multi buffering

        He also discovered and fixed some bugs in doing so.  When pulling in
        his patches, I also found a few minor bugs as well and fixed them.
      
        This also includes a compile fix for some archs that select the ring
        buffer but not tracing.
      
        I based this off of the last patch you took from me that fixed the
        merge conflict error, as that was the commit that had all the changes
        I needed for this set of changes."
