Hi everybody, I was reading this article: http://www.cs.fsu.edu/~baker/devices/notes/spinlock.html and I noticed this excerpt: > If you strip off the debugging extras, and get down to the raw > spinlock object for the SMP case for the i386, it looks like this: > > typedef struct { > unsigned int slock; > } raw_spinlock_t; > > Earlier versions of Linux had the raw lock value field slock > declared as "volatile". Do you know what that means? Why is > that not done in the 2.6.25 kernel? But, sadly, the writer doesn't give the answer. So, obviously, my question is: Why slock is not declared as "volatile" in the 2.6.25 kernel?
