NAME         top

       ioctl_xfs_goingdown - shut down an XFS filesystem

SYNOPSIS         top

       #include <xfs/xfs_fs.h>

DESCRIPTION         top

       Shuts down a live XFS filesystem.  This is a software initiated hard

           XFS_FSOP_GOING_FLAGS_DEFAULT
                  Flush all dirty data and metadata to disk, flush pending
                  transactions to the log, and shut down.

           XFS_FSOP_GOING_FLAGS_LOGFLUSH
                  Flush all pending metadata transactions to the log and
                  shut down, leaving all dirty data unwritten.

           XFS_FSOP_GOING_FLAGS_NOLOGFLUSH
                  Shut down immediately, without writing pending
                  transactions or dirty data to disk.

RETURN VALUE         top
