unpack_reference_block(9)

💖 unpack_reference_block(9) 💖

okay bestie, welcome to the Kernel API Manual entry for unpack_reference_block(9) — this one is short and sweet, no cap. ✨

🌸 NAME 🌸

unpack_reference_block — Unpack reference counts blocks into the internal memory structure. 🎀

✨ SYNOPSIS ✨

here's the signature, exactly as it is, don't come for me:

       void unpack_reference_block (struct packed_reference_block *packed ,
       struct reference_block *block );

🎀 ARGUMENTS 🎀

• packed — the written reference block that's about to get unpacked. 💅
• block — the internal reference block that's getting loaded. 🦋

🌈 SEE ALSO 🌈

okay this list is literally the whole group chat — every single reference, preserved exactly, no edits, no skips:
