key_write(9)

key_write(9) 💖

okay so this is a page from the Kernel API Manual and it's short and sweet, which honestly? we love that for us. no cap, it's giving "one job, done correctly." ✨

🌸 NAME 🌸

key_write — transform a key from in-memory format. that's it. that's the whole gig, bestie 🎀

🦋 SYNOPSIS 🦋

void key_write (const struct ubifs_info *c , const union ubifs_key *from
, void *to );

like… three args, no return value, zero drama 🙈

💜 ARGUMENTS 💜

• c — the UBIFS file-system description object. it's the context, the backstage pass, the "iykyk" of this whole operation 👑
• from — the key you wanna transform. this is your main character right here ⭐
• to — where the result gets stored. it's the destination, the group chat the message gets forwarded to 💌

🧚 SEE ALSO 🧚

bestie there is a whole friend group here, and honestly they're all iconic in their own way. go say hi to:

key_mask_hash(9), key_r5_hash(9), key_test_hash(9), ino_key_init(9), ino_key_init_flash(9), lowest_ino_key(9), highest_ino_key(9), dent_key_init(9), dent_key_init_hash(9), dent_key_init_flash(9), lowest_dent_key(9), xent_key_init(9), xent_key_init_flash(9), lowest_xent_key(9), data_key_init(9), highest_data_key(9), trun_key_init(9), invalid_key_init(9), key_type(9), key_type_flash(9), key_inum(9), key_inum_flash(9), key_hash(9), key_hash_flash(9), key_block(9), key_block_flash(9), key_read(9), key_write_idx(9), key_copy(9), keys_cmp(9), keys_eq(9), is_hash_key(9), key_max_inode_size(9) 💅

all of these live in the kernel file ./fs/ubifs/key.h btw, so that's your hangout spot 🌈

ngl the whole page is literally just "convert a key out of in-memory format" — no flags, no exit codes, no scary warnings. a rare low-stakes slay 💀🫶

and that's the whole page, bestie!! this one came from ./fs/ubifs, the October 2026 version, and it's filed under key_write(9) — mwah, go forth and transform keys ✨🍓💜
