💅 qla4xxx_sysfs_ddb_delete — a Kernel API Manual moment

okay so bestie, this is a page from the Kernel API Manual, and the star of the show is qla4xxx_sysfs_ddb_delete(9). Yes it's a mouthful. Yes it slays. Let's get into it 🫶

---

✨ NAME ✨

qla4xxx_sysfs_ddb_delete — literally just: delete a firmware DDB entry. That's the whole vibe. 💀

---

🌸 SYNOPSIS 🌸

int qla4xxx_sysfs_ddb_delete (struct iscsi_bus_flash_session *fnode_sess
);

like. she takes one (1) pointer and returns an int. iconic behavior honestly.

---

🎀 ARGUMENTS 🎀

• fnode_sess — pointer to the session attrs of the flash ddb entry. that's the thing you're yeeting. 🗑️✨

---

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓: this function invalidates the flash ddb entry at the given index. that's it, that's the whole plot. no cap, no extras, she does one job and she does it. 💅
