nilfs_prepare_write_logs(9)

💅 nilfs_prepare_write_logs(9) — Kernel API Manual ✨

🌸 NAME 🌸

nilfs_prepare_write_logs — okay bestie, this one is literally “prepare to write logs.” No cap. 🫶

✨ SYNOPSIS ✨

void nilfs_prepare_write_logs (struct list_head *logs , u32 seed );

🎀 ARGUMENTS 🎀

• logs — the logs you’re getting ready for writing, bestie. 💖
• seed — the checksum seed value. ⭐

🦋 DESCRIPTION 🦋

Okay so here’s the vibe: nilfs_prepare_write_logs adds checksums and prepares the block buffers/folios for writing logs. ✨ In order to stabilize folios of memory-mapped file blocks by putting them in writeback state before calculating the checksums, it first prepares to write payload blocks other than segment summary and super root blocks — the ones where the checksums will be embedded. 💅
