gfs2_rgrp_used_recently(9)

💖 gfs2_rgrp_used_recently(9) 💖

Welcome to the Kernel API Manual, bestie — section 9 is giving main character energy today, and the star of the page is gfs2_rgrp_used_recently.

🌸 NAME 🌸

gfs2_rgrp_used_recently — test if an rgrp has been used recently. That's the whole quest, and honestly? Iconic.

✨ SYNOPSIS ✨

bool gfs2_rgrp_used_recently (const struct gfs2_blkreserv *rs , u64 msecs );

🎀 ARGUMENTS 🎀

• rs — the block reservation with the rgrp to test. You're handing over the reservation so the function knows which rgrp is getting the vibe check.
• msecs — the time limit in milliseconds. This is your "recently" window, bestie.

👑 RETURN 👑

True if the rgrp glock has been used within the time limit. No cap.
