1) Given a virtual inode, how do I get the block list associated to it? I tried to convert the inode to an ext3_inode_info using EXT3_I(), but I can't find the block list there. block list is in the ext3_inode_info struct: struct ext3_inode_info { __le32 i_data[15]; /* this is block list */ __u32 i_flags; ....... }; and i do'nt know the second question. <div class="gmail_quote">2009/6/6 Donato Capitella <<a href="mailto:d.capitella@tin.it">d.capitella@tin.it</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi there, I just started hacking the linux kernel. I need to know how to do 2 things: 2) Given a block number, how do I write data to that block? Is there any function like write_to_block(int block_n, char *buf, int bytes) or something? Thank you in advance, I'm young and this is my first approach to kernel programming and don't know where to find documentation.
