hi,<br><br>in kernel space ,if i get the i_ino(inode mumber ) of a file, and next
how could i get the block number of this file? in VFS layer the inode
struct haven't i_block[] array to point to the blocks. but in
ext3_inode struct, it has. what's the relationship between the VFS
inode and ext3_inode?<img src="http://www.linuxforums.org/forum/images/smilies/confused.gif" alt="" title="Confused" class="inlineimg" border="0"><br clear="all"><br><br>how do i get the block number of a file ?  <span style="font-size: 12pt; font-family: "Times New Roman"; letter-spacing: 0.5pt;" lang="EN-US">the path is as follow:<br>
