✨ struct zfcp_dbf_hba_uas — Kernel API Manual ✨

okay so bestie, we're in the kernel API manual, and today's main character is struct zfcp_dbf_hba_uas(9) 💅 like yes we're literally reading kernel headers for fun now, that's the vibe 🎀

🌸 NAME 🌸

struct zfcp_dbf_hba_uas — the trace record for the sysfs unit add store 🫶

like, that's the whole thing. that's what it is. a little struct that shows up in your trace record when somebody does a unit add store through sysfs ✨

struct zfcp_dbf_hba_uas {
    u64 wwpn;
    u64 fcp_lun;
    u32 ret;
 };

no cap, that's the entire shape of it — two u64s and a u32, tiny but iconic 👑
