is_exact_re...ournal_block(9)

💅 is_exact_re...ournal_block(9) — like, the Kernel API Manual, but make it make sense 🎀

okay bestie, so this little icon lives in the Kernel API Manual and its whole personality is "does this block match the exact one we're looking for?" — that's it, that's the vibe. no cap. ✨

---

🌸 NAME 🌸

is_exact_recovery_journal_block — determine whether the given header describes the exact block indicated. literally just a yes/no girlie. 💖

---

🦋 SYNOPSIS 🦋

bool is_exact_recovery_journal_block (const struct recovery_journal
*journal , const struct recovery_block_header *header ,
sequence_number_t sequence );

---

🎀 ARGUMENTS 🎀

• journal — the journal to use. like, the main character of this whole situation. 👑
• header — the unpacked block header to check. she's giving "please verify me" energy. 🔥
• sequence — the expected sequence number. the number we're manifesting. ⭐

---

💜 RETURN 💜

True if the block matches. that's the whole answer. slay. ✅

💀 reminder: this is a kernel API page, so those (9) bits mean manual section 9, not "9 out of 10, would recommend". iykyk.
