2019-02-27samples: bpf: fix: broken sample regarding removed functionDaniel T. Lee
Currently, running sample "task_fd_query" and "tracex3" occurs the following error. On kernel v5.0-rc* this sample will be unavailable due to the removal of function 'blk_start_request' at commit "a1ce35f". (function removed, as "Single Queue IO scheduler" no longer exists) $ sudo ./task_fd_query failed to create kprobe 'blk_start_request' error 'No such file or directory' This commit will change the function 'blk_start_request' to 'blk_mq_start_request' to fix the broken sample.
