Hello All, I think still this is not being replaced with assert_spin_lock_held() call as suggested by Linus.It is worth to replace these calls. Sanjeev Sharma -- View this message in context: http://linux-kernel.2935.n7.nabble.com/Is-spin-is-locked-safe-to-use-with-BUG-ON-WARN-ON-tp654800p921

[PATCH v3 20/23] perf: itrace: Infrastructure for sampling instruction flow traces
