efivar_entry_delete(9)

🎀 NAME 🎀

okay so bestie, welcome to efivar_entry_delete(9) from the Kernel API Manual — yes, the manual name is right there, cute. This function is literally here to delete variable, periodt. 💅

• efivar_entry_delete — delete variable 🌸

✨ SYNOPSIS ✨

int efivar_entry_delete (struct efivar_entry *entry );

🦋 ARGUMENTS 🦋

• entry — entry containing variable to delete 🫶

🌸 DESCRIPTION 🌸

Delete the variable from the firmware. That's the main character move. ✨

It is the caller's responsibility to free entry (by deleting the dentry/inode) once we return. No cap — that cleanup is on you, not this function. 😭

Return vibes: 0 on success, -EINTR if we can't grab the semaphore, and a converted EFI status code if set_variable fails. Lowkey important, highkey useful. 💖

🫶 reminder: after this returns, freeing entry is your job — and the way you do it is by deleting the dentry/inode. Don't forget, bestie.
