How to mount own file system in linux

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,
I want to create new file system in linux 2.6.10 kernel just to print the super block information. Can you suggest me where I can get some good documents to proceed or any dummy code if any.

I have tried this with the following code but it gives some warning messages during compilation. The file system is registered but during the mount command segmentation fault occurs.

#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/version.h>
#include <linux/fs.h>
#include <linux/sched.h>

static struct super_block *rfs_read_super( struct super_block *sb, void *buf, int size);
static struct file_system_type rfs = {"rfs", 0, rfs_read_super, NULL};
/*--------------------------------------------------------------------------------------------*/ static struct super_block *rfs_read_super( struct super_block *sb, void *buf, int size) {
      printk("rkfs: read_super returning a valid super_block\n" );
      sb->s_blocksize = 1024;
      sb->s_blocksize_bits = 10;
      return sb;
}
/*--------------------------------------------------------------------------------------------*/
int init_module(void) {
      int err;
      err = register_filesystem(&rfs);
      printk("rkfs: file system registered\n" );
      return err;
}
/*--------------------------------------------------------------------------------------------*/
void cleanup_module(void) {
      unregister_filesystem(&rfs);
      printk("rkfs: file system unregistered\n" );
}
/*--------------------------------------------------------------------------------------------*/
MODULE_LICENSE("GPL");

regards,
chinmaya
