<DIV><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <FONT
color=#000000 size=2>Dear sir:<BR>&nbsp;&nbsp;&nbsp;&nbsp; I am very sorry to
bother you. I'm a senior student <BR>of Peking University in China.I am reading
the source <BR>code of Linux.I am the classmate of Zhangsu,a student
has<BR>asked you some questions about the Linux kernel. He told <BR>me I could
find help from you.Recently I have encountered <BR>a lot difficulty in
understanding its meaning.I wonder <BR>if you ,sir, would like to reply my
questions or give me <BR>some instructs when you are free.Thank you very much
for <BR>your help.<BR>&nbsp;&nbsp;&nbsp;&nbsp; These are my
questions:<BR>&nbsp;&nbsp;&nbsp;&nbsp; 1. What is the meaning of
&quot;d_covers&quot; domain in the
<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &quot;dentry&quot;
struct?<BR>&nbsp;&nbsp;&nbsp;&nbsp; 2. What is the difference between an varible
whose <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; type is &quot;kdev_t&quot;
and&nbsp; another whose type is &quot;dev_t&quot;?<BR>&nbsp;&nbsp;&nbsp;&nbsp;
3. What is the effect of the &quot;dquot&quot; struct ?&nbsp;
<BR>&nbsp;&nbsp;&nbsp;&nbsp; 4. What is the relations between
&quot;super_block&quot;,&quot;dev&quot;,<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&quot;dentry&quot; and &quot;inode&quot;?Is a super_block
<BR>&nbsp;&nbsp;&nbsp;&nbsp; 5. When the system runs at the end of the
&quot;start_kernel&quot; <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (in
main.c)it starts a &quot;init_task&quot;, what does this
<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; task do and how?I know it's
task_struct has been <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; filled, but
I don't know where is its code (the
<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; task_struct is too
complex)<BR>&nbsp;&nbsp;&nbsp;&nbsp; 6. And how about the book &quot;Linux
Kernel Internals or <BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Inside the
Linux Kernel&quot;and what version of the
<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Linux does it talk
about?<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
