NAME
     VFS_STATFS — return file system status

SYNOPSIS
     #include <sys/param.h>
     #include <sys/mount.h>
     #include <sys/vnode.h>

     int
     VFS_STATFS(struct mount *mp, struct statfs *sbp);

DESCRIPTION
     The VFS_STATFS() macro returns various pieces of information about the
     file system, including recommended I/O sizes, free space, free inodes,
     etc.

     The arguments it expects are:

     mp   The file system.

     sbp  A statfs structure, as defined by <sys/mount.h>, into which informa‐
          tion is placed about the file system.

     The fields of struct statfs related to the file system are as follows:

     f_type         Type of file system.

     f_flags        A copy of mount exported flags.

     f_bsize        Fragment size.

     f_iosize       Optimal transfer block size.

     f_blocks       The total number of data blocks in the file system.

     f_bfree        The number of free blocks in the file system.

     f_bavail       The number of free blocks available to non-superuser pro‐
                    cesses.

     f_files        The total number of file nodes in the file system.

     f_ffree        The number of free nodes available to non-superuser pro‐
                    cesses.

     f_syncwrites   The number of synchronous writes since the file system was
                    mounted.

     f_asyncwrites  The number of asynchronous writes since the file system
                    was mounted.

     f_syncreads    The number of synchronous reads since the file system was
                    mounted.

     f_asyncreads   The number of asynchronous reads since the file system was
                    mounted.

     f_namemax      The maximum file name length for this file system.

     f_owner        The user ID of the user that mounted the file system.

     f_fsid         Unique file system ID.

     f_fstypename   The file system type name; a string of at most MFSNAMELEN
                    bytes.

     f_mntfromname  The device name the file system was mounted from; a string
                    of at most MNAMELEN bytes.

     f_mntonname    The name of the directory on which the file system is
                    mounted; a string of at most MNAMELEN bytes.
