STRUCT UBIFS_GLOBAL_DEBUG_INFO(9)

🌸 NAME 🌸

struct ubifs_global_debug_info — the global (not per-FS, okay? global) UBIFS debugging information. It's giving "one struct to rule all the debug switches" energy 💅

This page lives in the Kernel API Manual (section 9), so like… kernel devs only, bestie 🫶

✨ SYNOPSIS ✨

struct ubifs_global_debug_info {
    unsigned int chk_gen:1;
    unsigned int chk_index:1;
    unsigned int chk_orph:1;
    unsigned int chk_lprops:1;
    unsigned int chk_fs:1;
    unsigned int tst_rcvry:1;
 };

Look at all those :1 bitfields, literally one bit each, so frugal, so iconic 🌈

👑 Members 👑

Every single one of these is a single-bit flag, and each one is a whole vibe check for a different corner of UBIFS:

• chk_gen — flips on when general extra checks are enabled. The default-era bestie of the group 🎀
• chk_index — flips on when index xtra checks are enabled. Yes, xtra. With an x. We don't question the kernel's spelling choices 💀
• chk_orph — flips on when orphans extra checks are enabled. Someone's gotta check on the orphans 😭
• chk_lprops — flips on when lprops extra checks are enabled. Lprops nation rise 🦋
• chk_fs — flips on when UBIFS contents extra checks are enabled. Big "check the whole fit before you leave the house" energy 🔥
• tst_rcvry — flips on when UBIFS recovery testing mode is enabled. Recovery era, tst_rcvry era, we love to see it ⭐

Reminder bestie: this struct is global — not per-FS. It's not going in your filesystem's little profile, it's the whole squad's settings 💖

🔥 SEE ALSO 🔥

• Kernel file ./fs/ubifs/debug.h
• struct ubifs_debug_info(9) — the per-FS sibling, go say hi 👋

And that's the whole page, no cap. This masterpiece was served to you by ./fs/ubifs, October 2026, and the header/footer text that says struct ubifs...l_debug_info(9) (yes the truncation is canon, we stan a mysterious ellipsis) 🧚💜
