函数名称:Creates the child task context and tries to inherit the event-group.* Clears @inherited_all on !attr.inherited or error. Note that we'll leave* inherited_all set when we 'fail' to inherit an orphaned event; this is
函数原型:static int inherit_task_group(struct perf_event *event, struct task_struct *parent, struct perf_event_context *parent_ctx, struct task_struct *child, int ctxn, int *inherited_all)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct perf_event * | event | |
struct task_struct * | parent | |
struct perf_event_context * | parent_ctx | |
struct task_struct * | child | |
int | ctxn | |
int * | inherited_all |
12227 | 如果非inherit则 |
12228 | inherited_all等于0 |
12229 | 返回:0 |
12232 | child_ctx等于perf_event_ctxp[ctxn] |
12233 | 如果非child_ctx则 |
12240 | child_ctx等于alloc_perf_context(pmu, child) |
12244 | perf_event_ctxp[ctxn]等于child_ctx |
12250 | 如果ret则inherited_all等于0 |
12253 | 返回:ret |
