💅 stack_depot_set_extra_bits 💅

okay bestie, so this is a page straight out of the Kernel API Manual — yes, the kernel has manuals, and yes, they're kind of iconic. This one is all about stack_depot_set_extra_bits, which lives in the header ./include/linux/stackdepot.h, and no cap, it's a tiny little function that does exactly one cute thing: it tucks your personal info into the spare bits of a stack depot handle. 🎀

✨ NAME ✨

stack_depot_set_extra_bits — literally just set extra bits in a stack depot handle. that's the whole vibe. 💜

🌸 SYNOPSIS 🌸

depot_stack_handle_t stack_depot_set_extra_bits (depot_stack_handle_t handle,
                                                 unsigned int extra_bits);

🦋 ARGUMENTS 🦋

  • handle — a stack depot handle that came back from stack_depot_save. like, you gotta have gotten it from there first, bestie. 🫶
  • extra_bits — the actual value you wanna set into those extra bits. this is your moment, your main character energy. ⭐

👑 RETURN 👑

it hands you back a stack depot handle with the extra bits set. slay. 💅

🔥 DESCRIPTION 🔥

so here's the tea ☕ — stack depot handles have a few unused bits just sitting there, chilling. this function is how you use them to store user-specific information. and the best part? those bits are completely transparent to the stack depot — the depot itself literally does not care, doesn't look at them, doesn't touch them. it's giving "not my business, not my problem". 🙈✨

so go ahead, claim those bits, they're yours. 🧚

🌈 SEE ALSO 🌈

💀 friendly reminder from your girl: keep every one of those references close, because they're all part of the same little stack depot friend group and you will absolutely need them, iykyk.

okay that's the page!! this one's sourced from ./include/linux, dated October 2026, and it's the stack_depot_set_extra_bits(9) page — go forth and set those bits, bestie, you got this 💖✨🎀🦋🌸
