vdo_pack_slab_journal_entry(9)

💅 NAME 💅

Okay bestie, welcome to vdo_pack_slab_journal_entry(9) from the Kernel API Manual. This is literally the function that generates the packed encoding of a slab journal entry — the NAME section said it, so we're saying it: vdo_pack_slab_journal_entry — generate the packed encoding of a slab journal entry. Slay. 💖

✨ SYNOPSIS ✨

Here's the exact signature, no cap — don't let the line wrap gaslight you:

void vdo_pack_slab_journal_entry (packed_slab_journal_entry *packed ,
       slab_block_number sbn , bool is_increment );

🎀 ARGUMENTS 🎀

• packed — the packed_slab_journal_entry entry into which to pack the values. It's the destination, bestie. 🫶
• sbn — the slab_block_number of the entry to encode. That's the slab block number, periodt.
• is_increment — the increment flag. That's it, that's the flag. 💅
