Hi all,
I was going through the code of __wait_event in sched.c [ kernel 2.2.19] and i
came across a MACRO mb(), and it was defined in asm-i386/system.h as following
#define mb() __asm__ __volatile__ ("lock; addl $0,0(%%esp)": : :"memory")
I don't know what this MACRO does?? [ I actually don't know assembly ]
Can anyone help me??
TIA
Regards
Ketan
