Subject: flushing tlb in try_to_swap_out
Date: Mon, 1 Sep 2003 14:37:39 -0400 (EDT) [thread overview]
Message-ID: <Pine.GSO.4.51.0309011437050.15065@aria.ncl.cs.columbia.edu> (raw)
I see that in try_to_swap_out() (linux 2.4.19), the page that is being
unmapped from a process is flushed out. But try_to_swap_out() is executed
in the context of kswapd. And also whenever a context switch takes place
the whole tlb is flushed out. So is this flushing done just becuase linux
uses lazy_tlb_flush during process context switch ?
thanks a lot,
Raghu
