STRUCT NILFS_RECOVERY_INFO(9)

🌸 struct nilfs_recovery_info(9) 🌸

okay so this is from the Kernel API Manual, bestie — and it's literally the struct nilfs_recovery_info page, aka your recovery-information era 💅

---

✨ NAME ✨

struct nilfs_recovery_info — Recovery information. that's it, that's the vibe 🫶

---

🦋 SYNOPSIS 🦋

struct nilfs_recovery_info {
    int ri_need_recovery;
    sector_t ri_super_root;
    __u64 ri_cno;
    sector_t ri_lsegs_start;
    sector_t ri_lsegs_end;
    u64 ri_lsegs_start_seq;
    struct list_head        ri_used_segments;
    sector_t ri_pseg_start;
    u64 ri_seq;
    __u64 ri_segnum;
    __u64 ri_nextnum;
 };

no cap, every single field is right there 👑 copy it exact, we don't improvise structs.

💖 MEMBERS 💖

okay the members walk-through, and yes we're doing all of them, main character energy only ✨

• ri_need_recovery — the recovery status. it tells you whether recovery is even in its little to-do list 🎀
• ri_super_root — block number of the last super root 🌈
• ri_cno — number of the last checkpoint. iconic checkpoint behavior ⭐
• ri_lsegs_start — the region for roll-forwarding, start block number 💫
• ri_lsegs_end — the region for roll-forwarding, end block number. and yes it pairs with ri_lsegs_start like the duo they are 🫶
• ri_lsegs_start_seq — sequence value of the segment at ri_lsegs_start 🔥
• ri_used_segments — list of segments to be mark active 👀 (that's the original wording, we keep it fr fr)
• ri_pseg_start — block number of the last partial segment 🦋
• ri_seq — sequence number on the last partial segment 🌸
• ri_segnum — segment number on the last partial segment 💜
• ri_nextnum — next segment number on the last partial segment 💅

ngl, if you're looking at these fields and going "wait which is the last partial segment", it's literally ri_seq, ri_segnum, and ri_nextnum — they all live on the last partial segment, bestie, they're a package deal 🎀

and that's the whole page, no crumbs left behind 🙈 source is ./fs/nilfs2, dated October 2026, and it's the struct nilfs_recovery_info(9) page — slay, go read your kernel headers, ily, bye 💜✨
