Subject: native_save_fl taking good amount of time in profile

I have collected a profile on the whole system. But the only thing
that is really running is a mysql database server. I have noticed that
there is a function in kernel that took 5% of the overall running
time. what does native_save_fl do ? does it make sense that
native_save_fl takes the most amount of time among all kernel
functions ?

Thank
