A simple question.

Dear all,

After I compile and upgrade to a newer Kernel, do I need to copy the
System.map from /usr/src/linux/ to /boot/System-xxxx and link it to
System.map?

Thanks in advance
Hai Xu

yes, you do. but System.map is only needed to do symbol lookups, for
times like debugging.

note most distributions link /boot/System.map to the correct System.map
(in boot) on startup. if your's does not, its a simple script:

ln -sf /boot/System.map-`uname -r` /boot/System.map

If you do a make install, it will be copied to /boot directory
automatically;-)

A simple question

[ed Wang]

I saw a lot of function define as _inline_ in Linux
kernel.  What does the term _inline_  mean?  For the
assembly inline statement, _asm_ should do the work.

Thanks for the help!

Feel free to correct me if I'm wrong...

 From my understanding, inline has asolutely nothing to do with 
assembly.  When a function is declared as inline, you're basically 
telling the compiler that anytime it runs into this function being 
called, to replace that call with the body of the function (to eliminate 
the overhead of making the function call).  It's great for small, little 
operations that are done extremely often.
