From add68832f851b88d8d55b3c3e302d2f908e87bb2 Mon Sep 17 00:00:00 2001 From: Neil Brown Date: Fri, 14 Sep 2007 10:28:08 -0400 Subject: [PATCH] Correctly close old nfsd/lockd sockets. Commit 74cc458c5bf8b404d7b4a1365595cfe4e1809a0b added a bias to sk_inuse, so this test for an unused socket now fails. So no sockets get closed because they are old (they might get closed if the client closed them). This bug has existed since 2.6.21-rc1. Thanks to Wolfgang Walter for finding and reporting the bug.
