what is the medium who provides mapping between indoe number and datablock
 

Hi all

having one confusion ?

As we know
each file has inode

inode contains two things
metadata
actual data

and there is mapping between inode number and data block

but who provides mapping between this two that is inode number and data block.

i think it is kernel...right

if it is not the please tell me..i m confused

It's the filesystem layer within the kernel.
