• d2e614cb0   samples: bpf: fix: broken sample regarding removed function ... Browse Code »

  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.

  This is mostly to test kprobe/uprobe which needs kernel headers.
