lpfc_check_inactive_vmid(9)

📦 version 7.3.1, in nixpkgs unstable

💖 lpfc_check_inactive_vmid — the VMID inactivity checker ✨

okay so real talk, this one lives in the Linux kernel API manual (section 9, the kernel-doc girlies), and she's a little function with a big job. come sit with me 🫶

🌸 NAME 🌸

lpfc_check_inactive_vmid — the VMID inactivity checker, no cap 💅

🦋 SYNOPSIS 🦋

void lpfc_check_inactive_vmid (struct lpfc_hba *phba );

literally that's it. void in, void out, one argument, very demure, very mindful 🎀

🌈 ARGUMENTS 🌈

  • phba — pointer to the hba context object. that's the homegirl that holds all the context, she needs to be passed in so the function knows what we're even talking about 💜

✨ DESCRIPTION ✨

okay so picture this: this function gets called from the worker thread 👑 and its whole entire vibe is "is this VMID table entry still relevant or can we let her go?"

specifically, it's checking whether an entry in the VMID table can be released, because there was no I/O activity seen from that particular VM for the specified time. so like, the VM ghosted the I/O queue and now we're doing a vibe check on whether to keep her around 🫥

and when that happens — and like, bestie, when it happens it happens — the entry in the table gets released, and the resources on the switch get cleared too. two birds, one function call, slay 🔥

so tl;dr: quiet VM → entry released → switch resources cleared. she's a cleanup icon, periodt ✨

💀 SEE ALSO 💀

kernel file: ./drivers/scsi/lpfc/lpfc_hbadisc.c — that's where she lives 🏠

and now the whole extended friend group, because apparently everyone in this file knows everyone. buckle up, this is a long group chat 💅

iykyk, it's a whole ecosystem over in drivers/scsi/lpfc 🧚

that's the page, bestie, go forth and check those inactive VMIDs 💖
