self_check_in_pq(9) 💖

okay so this is a Kernel API Manual page, and the main character is self_check_in_pq — the little function that checks if a wear-leveling entry is in the protection queue. no cap, that's the whole plot. 🫶

✨ NAME ✨

self_check_in_pq — check if wear-leveling entry is in the protection queue. 💅

🦋 SYNOPSIS 🦋

int self_check_in_pq (const struct ubi_device *ubi , struct ubi_wl_entry
*e );

💅 ARGUMENTS 💅

• ubi — the UBI device description object, bestie. it's giving "the device info we need." 🎀
• e — the wear-leveling entry to check. literally the entry in question. 👀

🔥 DESCRIPTION 🔥

so here's the vibe check: this function returns 0 if e is in ubi->pq, and it returns -EINVAL if it is not in there. periodt. that's the whole return situation. no extra lore, no side quests. 😭
