goal_in_my_reservation(9)

💅 NAME 💅

okay bestie, welcome to goal_in_my_reservation(9) from the Kernel API Manual ✨ Officially the NAME line is just goal_in_my_reservation with a lil dash and no description after it — she’s mysterious like that, no cap 💅

---

✨ SYNOPSIS ✨

int goal_in_my_reservation (struct ext2_reserve_window *rsv ,
ext2_grpblk_t grp_goal , unsigned int group , struct super_block * sb );

---

🎀 ARGUMENTS 🎀

• rsv — the inode’s reservation window, aka the VIP section 🫶
• grp_goal — the given goal block, relative to the allocation block group
• group — the current allocation block group
• sb — the filesystem super block

---

🦋 DESCRIPTION 🦋

So here’s the vibe check: this function tests whether the given goal block — group-relative, bestie — is inside the file’s own block reservation window range. It’s giving “are you on the list?” energy 👑

If the reservation window is outside the goal allocation group, return 0 — bouncer says no 🚫

Now, grp_goal (the given goal block) could be -1, which means there’s no specific goal block. In that case, always return 1 — special-case slay, periodt ✨

If the goal block is within the reservation window, return 1; otherwise, return 0. That’s the whole test, and it ate 💅
