From cfce08c6bdfb20ade979284e55001ca1f100ed51 Mon Sep 17 00:00:00 2001 From: Christian Pulvermacher Date: Tue, 23 Mar 2010 11:51:38 -0500 Subject: [PATCH] ecryptfs: fix error code for missing xattrs in lower fs If the lower file system driver has extended attributes disabled, ecryptfs' own access functions return -ENOSYS instead of -EOPNOTSUPP. This breaks execution of programs in the ecryptfs mount, since the kernel expects the latter error when checking for security capabilities in xattrs.
