vdo_pack_sla...block_header(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay bestie, this is the vdo_pack_sla...block_header(9) page from the Kernel API Manual πŸ’– and the star of the show is vdo_pack_slab_journal_block_header. Its whole job? Generate the packed representation of a slab block header. That's it, that's the vibe: take the header with the values, pack the values into the packed header, serve looks. Periodt.

πŸ“¦ SYNOPSIS πŸ“¦

void vdo_pack_slab_journal_block_header (const struct
slab_journal_block_header *header , struct
packed_slab_journal_block_header *packed );

It's giving void function realness β€” the signature is right there, no cap. Lowkey just pass it the two headers and let it do its little packing thing. πŸ’…

πŸŽ€ ARGUMENTS πŸŽ€

  • header β€” the header containing the values to encode. This is the source of the values, bestie.
  • packed β€” the header into which to pack the values. This is where the packed representation goes.
