Hengqi Chen 5a80bd075f block: introduce block_io_start/block_io_done tracepoints ... Currently, several BCC ([0]) tools (biosnoop/biostacks/biotop) use kprobes to blk_account_io_start/blk_account_io_done to implement their functionalities. This is fragile because the target kernel functions may be renamed ([1]) or inlined ([2]). So introduce two new tracepoints for such use cases.
