From 054d1c6535887376e73816e19be885d156732079 Mon Sep 17 00:00:00 2001 From: Marc Dionne Date: Wed, 11 Aug 2010 19:28:53 -0400 Subject: [PATCH] Linux: Rework statfs super block operations configure test The configure test to detect if the statfs super block operation needs a dentry argument is based on vfs_statfs, and assumes that its signature matches the one of the operation. In 2.6.36 this is no longer true and the test fails. Rework the test to actually test the operation we're interested in. This change is required for 2.6.36.
