megaraid_mbox_dpc(9)

✨ NAME ✨

okay so bestie, this is megaraid_mbox_dpc(9) from the Kernel API Manual — she's the tasklet to complete the commands from completed list. That's the whole gig. Slay. 💅

🎀 SYNOPSIS 🎀

it's giving:

void megaraid_mbox_dpc (unsigned long devp );

🌸 ARGUMENTS 🌸

• devp — pointer to HBA soft state. That's the one and only argument, bestie. 🫶

🦋 DESCRIPTION 🦋

So what does she do? She picks up the commands from the completed list and sends them back to the owners. Literally the cleanup bestie of this whole situation. 😭

Also: this is a reentrant function, and it does not assume any locks are held while it's being called. No cap — that's important. Don't come in here acting like locks are a given, because the manpage says nope. 💀
