    In the below link the struct ext2_inode_info has i_data
    lxr.linux.no/linux+v2.6.26/fs/ext2/ext2.h


    i_data contains the physical block number
    whenever the rm file is performed the info of block number in super block & bmap
    should not be updated. To stop this process which function should be called.
    The below link contains the list of .c files

    lxr.linux.no/linux+v2.6.26/fs/

    each .c file contains the functions and the explanations.But I need few more explanations for this. Mainly for the above process

    Reply plz

    Seems like you are dealing with ext2 file system.Why you want to prevent the update of super block and bitmap ? Incorrect superblock,bitmap will result in corrupting the system,and during next reboot fsck will be performed and all these files will be placed into lost+found directory.

    Regarding location of function , Please check source code of unlink() system call or read though the source code rm command.
