 Help with kernel source (struct list_head)
  I should miss the point... but I dont understand the
struct list_head {
      struct list_head *next, *prev;
from file /usr/src/linux/include/linux/list.h  :(

Dont understand where is the data nor how to access it. The
following macro of the same file seems to do the job, how?
#define list_entry(ptr, type, member) \
((type *)((char *)(ptr)-(unsigned long)(&((type *)0)->member)))

It seem to play an important role in struct inode
/usr/src/linux/include/linux/fs.h, but I cannot
figure how it work.

Help will be appreciated. Thank you!
