Q_XQUOTASYNC(2const)

💅 Q_XQUOTASYNC(2const) 💅

okay so bestie, welcome to the <rainbow>Q_XQUOTASYNC</rainbow> page of the manual — that's the 2const one, iykyk ✨

It's short. It's iconic. It does absolutely nothing. Let's get into it 🫶

✨ NAME ✨

Q_XQUOTASYNC — literally a no-op, bestie 💀

📚 LIBRARY 📚

Standard C library (libc, -lc) 🎀

🌸 SYNOPSIS 🌸

#include <xfs/xqm.h>      /* See quotactl(2) */
#include <sys/quota.h>

[[deprecated]]
int quotactl(QCMD(Q_XQUOTASYNC, type), NULL, 0, NULL);

#include <xfs/xqm.h>      /* See quotactl_fd(2) */
#include <sys/syscall.h>  /* Definition of SYS_* constants */
#include <unistd.h>

[[deprecated]]
int syscall(SYS_quotactl_fd, int fd, QCMD(Q_XQUOTASYNC, type));

like. look at that [[deprecated]]. the compiler is literally side-eyeing you 🙈

💖 DESCRIPTION 💖

so the lore is: this operation used to be the XFS quota equivalent of Q_SYNC(2const) — like, it would sync your quota info, cute, useful, slay.

but since Linux 3.4 it's a no-op. nothing happens. zero. nada. it's giving ghost 👻

why? because sync(1) handles writing quota information to disk now — on top of all the other filesystem metadata it already writes out. so Q_XQUOTASYNC just kinda stands there, main character energy with no lines 💅

🦋 RETURN VALUE 🦋

See quotactl(2) — go peek over there, bestie, that's where the deets live 🔥

lowkey the fastest manpage you'll ever read. no cap. Q_XQUOTASYNC is a no-op, and honestly? that's her whole personality 🫶
