is_block_dirty(9)

💅 is_block_dirty(9)

okay so bestie, welcome to the Kernel API Manual ✨ — yes, the actual kernel API manual, and yes, we're reading it together, because this little function is lowkey iconic and you're gonna get it in like thirty seconds. 🫶

---

✨ NAME ✨

is_block_dirty — check whether a recovery block is dirty 💖

---

🌸 SYNOPSIS 🌸

bool is_block_dirty (const struct recovery_journal_block *block );

---

🎀 ARGUMENTS 🎀

• block — the block to check. that's it. that's the whole vibe check right there. 🦋

---

💅 DESCRIPTION 💅

so like, this tells you whether the block has any uncommitted entries. and "uncommitted entries" is doing a lot of work here, bestie, because it means both:

• entries that were never written ✍️❌, and
• entries that were written but not yet acknowledged 👀

both of those count. no cap. 🔥

---

💜 RETURN 💜

True if the block has any uncommitted entries. simple. clean. slayed. 💅

ngl this is the kind of function that just answers a yes/no question and then minds its own business. main character energy fr fr. 👑
