Subject: swap_free() inside delete_from_swap_cache
Date: Fri, 5 Sep 2003 22:02:06 -0400 (EDT) [thread overview]
Message-ID: <Pine.LNX.4.44.0309052200580.440-100000@tehran.clic.cs.columbia.edu> (raw)
Why is swap_free() called inside delete_from_swap_cache() in linux
2.4.19? I believe delete_from_swap_cache() is called when we write a page
to the swap disk. swap_free() decreases the count of number of references
to that page. I am not understanding why should we decrement the count of
references when we are swapping the page to the disk.
Thanks,
Raghu
