💅 befs_find_brun_indirect 💅

okay so bestie, welcome to the befs_find_brun_indirect(9) page 💖 this is a Kernel API Manual situation, and we're about to go hunting for a block run in a datastream. no cap, it's lowkey adorable once you get it. 🦋

✨ NAME ✨

befs_find_brun_indirect — find a block run in the datastream 🌸

✨ SYNOPSIS ✨

int befs_find_brun_indirect (struct super_block *sb , const
befs_data_stream *data , befs_blocknr_t blockno , befs_block_run *run );

like, that's the whole vibe. four args, one int coming back at you. 🎀

✨ ARGUMENTS ✨

  • sb — the superblock, bestie. the big one. 👑
  • data — the datastream. yes, that datastream. 💫
  • blockno — the blocknumber we're trying to find. the whole point of the quest fr fr 🔍
  • run — the found run gets passed back through this pointer. it's giving "output parameter" main character energy 💅

✨ DESCRIPTION ✨

okay so here's the tea ☕ this function finds the block run that starts at file block number blockno, in the file represented by the datastream data — but only if that blockno is in the indirect region of the datastream. if it's not in that region, this is not the function for you, sorry not sorry 🙈

Return value is BEFS_OK if the blockrun is found, BEFS_ERR otherwise. slay. ✨

Algorithm (the way it actually does it, ngl): for each block in the indirect run of the datastream, read it in and search through it for search_blk. that's it. that's the whole method. 🧚

XXX: Really should check to make sure blockno is inside indirect region. 🫶 like… it just doesn't rn. that's a real note in the real source, bestie, so we're keeping it. 😭

✨ SEE ALSO ✨

go read the whole friend group, they're all icons, iykyk 🔥

and that's the page!! 💖 this little legend lives in ./fs/befs, and the date on it is October 2026 — so yeah, mark your calendar, screenshot it, send it to the group chat, and go find some block runs. periodt. 💅🎀🦋
