Q_XQUOTASYNC - no-op

Standard C library (libc-lc)

#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));

This operation was an XFS quota equivalent to Q_SYNC(2const), but it is no-op since Linux 3.4, as sync(1) writes quota information to disk now (in addition to the other filesystem metadata that it writes out).
