lpfc_alloc_sysfs_attr(9)

💖 NAME 💖

okay so bestie, this is the Kernel API Manual page for lpfc_alloc_sysfs_attr(9) — and the NAME line is literally: lpfc_alloc_sysfs_attr - Creates the ctlreg and mbox entries. That's it. That's the assignment. It creates those ctlreg and mbox entries, and we love a focused icon. ✨

✨ SYNOPSIS ✨

Here's the signature, exact, no cap — do not touch the punctuation, she is giving kernel API realness:

int lpfc_alloc_sysfs_attr (struct lpfc_vport *vport );

🎀 ARGUMENTS 🎀

• vport — address of lpfc vport structure. Yep, that's the one argument: a pointer to the vport struct. Lowkey simple, highkey essential. 🫶

💅 DESCRIPTION 💅

The return-code tea ☕ is: zero on success, and otherwise it's an error return code from sysfs_create_bin_file. No extra plot twists, bestie. If you get zero, slay. If not, the error came from sysfs_create_bin_file. Periodt. 🔥

mwah 💖 source/version: ./drivers/scsi/lpfc; date: October 2026; page: lpfc_alloc_sysfs_attr(9). That's the cute little footer sign-off, bestie — now go forth and respect the kernel API. 🧚‍♀️👑
