[PATCH v3 1/4] rcu/kasan: record and print call_rcu() call stack

2020-05-17 Thread Walter Wu
This feature will record the last two call_rcu() call stack and prints up to 2 call_rcu() call stacks in KASAN report. When call_rcu() is called, we store the call_rcu() call stack into slub alloc meta-data, so that the KASAN report can print rcu stack. [1]https://bugzilla.kernel.org/show_bug.cgi
