NAME
  mount - mounted filesystem data

SYNOPSIS
  mount [-f][-i] [-n pid|task] [mount|vfsmount|superblock|dev|dir|dentry|inode]

DESCRIPTION
  This command displays basic information about the currently-mounted
  filesystems.  The per-filesystem dirty inode list or list of open
  files for the filesystem may also be displayed.

     -f  dump dentries and inodes for open files in each filesystem; only
         supported on kernels prior to Linux 3.13.
     -i  dump all dirty inodes associated with each filesystem; only
         supported on kernels prior to Linux 2.6.32.

  For kernels supporting namespaces, the -n option may be used to
  display the mounted filesystems with respect to the namespace of a
  specified task:

     -n pid   a process PID.
     -n task  a hexadecimal task_struct pointer.

  Specific filesystems may be selected using the following forms:

    vfsmount  hexadecimal address of a filesystem vfsmount structure.
       mount  hexadecimal address of a filesystem mount structure (Linux 3.3
              and later).
  superblock  hexadecimal address of a filesystem super_block structure.
         dev  device name of a filesystem.
         dir  directory where a filesystem is mounted.
      dentry  hexadecimal address of an open dentry of a filesystem.
       inode  hexadecimal address of an open inode of a filesystem.
 
  The first column of the command output displays the filesystem's vfsmount
  structure address for kernels prior to Linux 3.3.  For Linux 3.3 and later
  kernels, the first column displays the filesystem's mount structure address,
  which contains an embedded vfsmount structure.

EXAMPLES
  Display mounted filesystem data:

    crash> mount
    VFSMOUNT SUPERBLK TYPE   DEVNAME   DIRNAME
    c0089ea0 c0088a00 ext2   /dev/root /    
    c0089cf0 c0088c00 proc   /proc     /proc
    c0089e10 c0088800 ext2   /dev/sda5 /boot
    c0089d80 c0088600 ext2   /dev/sda6 /usr
    c0089f30 c0088400 devpts none      /dev/pts
    c3f4b010 c0088200 ext2   /dev/sda1 /home
 
  On Linux 3.3 and later kernels, the filesystem's mount structure address
  is shown:

    crash> mount
         MOUNT           SUPERBLK     TYPE   DEVNAME   DIRNAME
