mas_set_range(9)

📦 version 7.3.1, in nixpkgs unstable

💖 mas_set_range — bestie's guide to moving your Maple Tree range 💖

okay so this is a page from the Kernel API Manual, section 9, and it's all about mas_set_range. slay, let's get into it 🎀

✨ NAME ✨

mas_set_range — set up the Maple Tree operation state so it points at a different index. that's it, that's the vibe 🦋

🌸 SYNOPSIS 🌸

void mas_set_range (struct ma_state *mas , unsigned long start ,
       unsigned long last );

literally just that. three args, no cap 💅

🎀 ARGUMENTS 🎀

  • mas — the Maple Tree operation state. this is your main character struct, the whole operation lives here 👑
  • start — the new start of the range in the Maple Tree. where the walk begins now, periodt 💫
  • last — the new end of the range in the Maple Tree. the other end, matching set 🌈

💜 DESCRIPTION 💜

okay so the tea: this moves the operation state so it refers to a different range. and like, heads up — the effect of this is that you start a walk from the top, fr fr. so it's giving "fresh start energy" 😭

if you actually want to move to an adjacent index instead of restarting from the top, go check out mas_next — that's your girl for that 🫶

not me dropping a subtle detail: the restart-from-the-top thing is literally what this does, so don't be surprised when your traversal isn't where you left it 💀

🔥 SEE ALSO 🔥

like. the whole maple tree friend group showed up to the function 💅✨

mwah, that's the page 🍓 this lil manual lives under ./include/linux, dated October 2026, and the page itself is mas_set_range(9) — go forth and set those ranges bestie 🧚‍♀️💖
