✨ gfs2_log_alloc_bio(9) — aka "the bio-birthday function" ✨

okay so bestie, this one's from the Kernel API Manual and it's lowkey iconic — we're in the gfs2 family, ./fs/gfs2 girlies rise 🫶

🌸 NAME 🌸

gfs2_log_alloc_bio — Allocate a bio 💅

🎀 SYNOPSIS 🎀

struct bio * gfs2_log_alloc_bio (struct gfs2_sbd *sdp , u64 blkno ,
bio_end_io_t *end_io , blk_opf_t opf );

🦋 ARGUMENTS 🦋

  • sdp — The super block. main character energy, honestly 👑
  • blkno — The device block number we want to write to. it's giving "destination: this block, no cap" 🎯
  • end_io — The bi_end_io callback. the little "we're done here" moment 🏁
  • opf — REQ_OP | op_flags. yes, both. together. slay ✨

💖 DESCRIPTION 💖

Allocate a new bio, initialize it with the given parameters and return it. that's it, that's the whole vibe — born, initialized, handed back to you, fresh out of the wrapper 🍓

🌈 RETURN 🌈

The newly allocated bio 💫 (not me handing you a whole bio and expecting you to be normal about it 😭)
