return_all_reservations(9)

🌸 NAME 🌸

Okay bestie, buckle up: this is return_all_reservations(9), straight out of the Kernel API Manual, and it is literally here to return all reserved blocks back to the rgrp. 💅✨

🦋 SYNOPSIS 🦋

void return_all_reservations (struct gfs2_rgrpd *rgd );

🎀 ARGUMENTS 🎀

• rgd — the rgrp that needs its space back 🫶

✨ DESCRIPTION ✨

So boom: we previously reserved a bunch of blocks for allocation, and now we need to give them back. This leaves the reservation structures intact, but removes all of their corresponding "no-fly zones". No cap, that’s the whole vibe. 💖
