STRUCT UBIFS_DATA_NODE(9)

✨ struct ubifs_data_node(9) ✨

okay bestie, so this is a page straight out of the Kernel API Manual, and it's literally all about struct ubifs_data_node — the data node. that's it, that's the vibe. a whole struct whose entire personality is "i hold data" 💅

🌸 SYNOPSIS 🌸

like, here's the whole shape of it, no cap:

struct ubifs_data_node {
    struct ubifs_ch ch;
    __u8 key[UBIFS_MAX_KEY_LEN];
    __le32 size;
    __le16 compr_type;
    __le16 compr_size;
    __u8 data[];
};

🎀 Members 🎀

okay so let's go through the whole group chat, member by member:

• ch — the common header. every struct needs its little foundational bestie 🫶
• key — the node key. it's a __u8 array of UBIFS_MAX_KEY_LEN, so like, respect the length, okay? 😌
• size — the uncompressed data size in bytes. that's a __le32 btw, in case you were wondering ✨
• compr_type — the compression type, and it's giving options: UBIFS_COMPR_NONE, UBIFS_COMPR_LZO, etc. pick your fighter 💅
• compr_size — the compressed data size in bytes, and listen, this one is only valid when data is encrypted. like, only then. don't come for it otherwise 🙈
• data — data. that's it. that's the description. iconic, honestly 👑
