💅 VDEVGONE(9) — the kernel dev manual, bestie edition 🎀

okay so this is vdevgone from the Kernel Developer's Manual and it's lowkey iconic for how much chaos it prevents. sit down, grab a strawberry drink 🍓, we're learning kernel stuff.

✨ NAME ✨

vdevgone — revoke all specified minor-numbered vnodes for a device. yes, all of them. she's thorough 💅

🌸 SYNOPSIS 🌸

#include <sys/param.h>
#include <sys/vnode.h>

void
vdevgone(int maj, int minl, int minh, enum vtype type);

literally just include those two headers and call her. that's it. no cap 🫶

🦋 DESCRIPTION 🦋

so the vdevgone() function will revoke all the vnodes that correspond to the specified minor number range, for the device whose major number is maj and whose type is type. the way that it just... cleans up the whole range. obsessed 😭✨

Its arguments are:

  • maj — the major number of the device. she's the main character here 👑
  • minl — the lowest minor number for the device to be revoked. the bottom of the range, bestie ⬇️
  • minh — the highest minor number for the device to be revoked. the top of the range ⬆️
  • type — the type of the device, and this must be one of these two, no improvising 🙈:
    • VBLK — device is a block device 🧱
    • VCHR — device is a character device 🎀
heads up! the endpoints specified by minl and minh are inclusive. so both ends are in the club, they both get an invite 💌
