Subject: 2.3.x swap cache seems to be a big leak
Date: Tue, 25 Apr 2000 05:03:01 -0700 [thread overview]
Message-ID: <200004251203.FAA04709@pizda.ninka.net> (raw)
__delete_from_swap_cache depends upon remove_inode_page doing
a put_page or similar to kill the reference of the swap cache
itself
We changed remove_inode_page during the page cache rewrite such
that is no longer puts the page, the caller does.
If I am right, this causes swap cache pages to never go away.
So if I haven't missed something clever going on here, this would
explain a lot of problems people have reported with swapping making
their machines act weird and eventually run out of ram.
Later,
