filesystems

NAME

       filesystems - details the table of configured file systems

SYNOPSIS

       linux/fs/filesystems.c

       From #include <linux/fs.h>

       struct file_system_type {
          struct super_block *(*read_super) (struct super_block *, void *, int);
          char *name;
          int requires_dev;
       };

DESCRIPTION

       This source code makes a  data  structure  call  file_sys-
       tems[]  which  contain  all the configured filesystems for
       the kernel.  It is used primarily in linux/fs/super.c  for
       many of the mounting of filesystems functions.

   The meanings
       This  first member, in struct file_system_type, is a func-
       tion  pointer  to  a  routine  that  will  read   in   the
       super_block.  A super_block generically means an i-node or
       special place on the device where  information  about  the
       overall filesystem in stored.

       The  name is just the string representation of the name of
       a specific filesystem, e.g. "ext2" or "minix".

       The final member, int requires_dev, is  a  boolean  value.
       If  it is true then the filesystem requires a block device
       (?).  For false, it is unclear what happens but an unnamed
       device is used, e.g. proc and nfs is this way.
