hi all ,

here is my query :

I made a module which access a disk inode using function named ext2_get_inode(). It returns structure pointer of disk block. I copied this structure pointer in a variable of same datatype as of disk inode which is present in my module.

Then I changed some fields of this disk inode ( eg. block numbers ) in the variable.

Now I want to write these changes back to disk. In other words , I want to write my module's variable back into disk inode in disk.

Have a look at the calls of. mark_inode_dirty(inode); __ext2_write_inode(inode, inode_needs_sync(inode));

Is there any method to do this?
