STRUCT POSIX_CPUTIMERS_WORK(9)

💖 struct posix_cputimers_work(9) — Kernel API Manual 💖

✨ NAME ✨

struct posix_cputimers_work — bestie, it’s the container for task work based posix CPU timer expiry. literally its whole job. 💅

🎀 SYNOPSIS 🎀

okay so here’s the struct, no cap, exactly like this:

struct posix_cputimers_work {
    struct callback_head    work;
    struct mutex            mutex;
    unsigned int            scheduled;
 };

💅 Members 💅

the three fields are giving very specific main-character energy:

• work — the task work to be scheduled. that’s it, that’s the field. ✨
• mutex — the mutex held around expiry in context of this task work. protect the vibe. 🔒
• scheduled — work has been scheduled already, no further processing. like, it’s done, stop asking. 💀

🌈 SEE ALSO 🌈

go look at the kernel file ./include/linux/posix-timers_types.h — yes, that exact path, don’t play — plus struct posix_cputimer_base(9) and struct posix_cputimers(9). iykyk 🦋
