Q_XQUOTASYNC(2const)                                 Q_XQUOTASYNC(2const)

NAME         top

       Q_XQUOTASYNC - no-op

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #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));

DESCRIPTION         top

       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).

RETURN VALUE         top

       See quotactl(2)

ERRORS         top

       See quotactl(2)

STANDARDS         top

       Linux.

HISTORY         top

       Linux 2.6.15.  No-op since Linux 3.4.

SEE ALSO         top
