STRUCT UBIFS_BUDG_INFO(9)

💖 NAME 💖

okay so this is the struct ubifs_budg_info(9) page from the Kernel API Manual — yes bestie, manual name right there near the top like a little name tag, section 9 and everything. 🏷️✨

struct ubifs_budg_info — UBIFS budgeting information. that's the whole vibe: UBIFS keeps its budgeting receipts in this struct, no cap. 🧾👑

🌸 SYNOPSIS 🌸

here's the exact shape of it, character for character — do not let the cute energy make you think you can rename a field, bestie:

       struct ubifs_budg_info {
           long long idx_growth;
           long long data_growth;
           long long dd_growth;
           long long uncommitted_idx;
           unsigned long long old_idx_sz;
           int min_idx_lebs;
           unsigned int nospace:1;
           unsigned int nospace_rp:1;
           int page_budget;
           int inode_budget;
           int dent_budget;
        };

💅 MEMBERS 💅

bestie, here's the whole roster — every single field, no skips, no "omg I forgot one" energy:

• idx_growth — the amount of bytes budgeted for index growth 💸
• data_growth — the amount of bytes budgeted for cached data ✨
• dd_growth — the amount of bytes budgeted for cached data that will make other data dirty 🫧
• uncommitted_idx — the amount of bytes that were budgeted for growth of the index, but which still have to be taken into account because the index has not been committed so far — yes, it's giving "pending receipts" 💀
• old_idx_sz — size of the index on flash 🔥
• min_idx_lebs — minimum number of LEBs required for the index 🎀
• nospace — non-zero if the file-system does not have flash space (used as optimization) 👑
• nospace_rp — the same as nospace, but additionally means that even reserved pool is full 😭
• page_budget — budget for a page (constant, never changed after mount) 🦋
• inode_budget — budget for an inode (constant, never changed after mount) 🌸
• dent_budget — budget for a directory entry (constant, never changed after mount) 💖
