STRUCT DEVLINK_HEALTH_REPORTER_OPS(9)

🩺 struct devlink_health_reporter_ops(9) — the Kernel API Manual, bestie edition 🩺

okay so quick vibe check: this page is from the Kernel API Manual, and it's literally all about struct devlink_health_reporter_ops — the reporter operations struct. think of it as the little instruction card your devlink health reporter fills out so the kernel knows how to poll it, dump it, diagnose it, and recover it. iconic behavior honestly 💅

✨ NAME ✨

struct devlink_health_reporter_ops — Reporter operations. that's it, that's the whole name section, she's short and sweet 🎀

---

🌸 SYNOPSIS 🌸

here's the struct in all her glory, copy-pasted exactly because we do NOT mess with code:

struct devlink_health_reporter_ops {
    char *name;
    int (*recover)(struct devlink_health_reporter *reporter, void
*priv_ctx, struct netlink_ext_ack *extack);
    int (*dump)(struct devlink_health_reporter *reporter, struct
devlink_fmsg *fmsg, void *priv_ctx, struct netlink_ext_ack *extack);
    int (*diagnose)(struct devlink_health_reporter *reporter, struct
devlink_fmsg *fmsg, struct netlink_ext_ack *extack);
    int (*test)(struct devlink_health_reporter *reporter, struct
netlink_ext_ack *extack);
    u64 default_graceful_period;
    u64 default_burst_period;
 };

look at her. five callbacks and two u64 defaults. main character energy fr fr 👑

🦋 Members 🦋

let's go member by member, no skips, no skimming:

• name — the reporter name. literally just her name tag 🏷️
• recover — callback to recover from a reported error, and if priv_ctx is NULL it runs a full recover. so like, priv_ctx set means a partial situation, NULL means go all in 💪
• dump — callback to dump an object, and if priv_ctx is NULL it runs a full dump. same energy as recover, different output 😌
• diagnose — callback to diagnose the current status. basically a health check-up 🩺
• test — callback to trigger a test event. yes bestie, we're poking it on purpose 🧪
• default_graceful_period — default min time (in msec) between recovery attempts. she's the cooldown timer ⏳
• default_burst_period — default time (in msec) for error recoveries before starting the grace period. so: burst first, then grace. periodt 🌈

ngl the msec thing matters — both of those defaults are in milliseconds, so don't go typing seconds in there 🙈
