attach new engine, or look up an attached engine
Synopsis
struct utrace_engine * utrace_attach_pid ( | struct pid * pid, |
| | int flags, |
| | const struct utrace_engine_ops * ops, |
| | void * data); |
Arguments
pid
struct pid pointer representing thread to attach to
flags
flag bits combined with OR, see utrace_attach_task
ops

data
engine private data pointer
Description
This is the same as utrace_attach_task, but takes a struct pid
pointer rather than a struct task_struct pointer. The caller must
hold a ref on pid, but does not need to worry about the task
staying valid. If it's been reaped so that pid points nowhere,
then this call returns -ESRCH.
