Comment 1 for bug 623087

It also seems that the filename created with 2.6.36-rc2 wasn't actually encrypted, although the folder _was_ mounted with ecryptfs and the option ecryptfs_enable_filename_crypto=y when the file was created. The unmounted file system shows as:

drwxr-xr-x 2 root root 4096 2010-08-24 08:46 ECRYPTFS_FNEK_ENCRYPTED.FWbHtjpMW4PshkQYqeqfXg.U0JuQXr1L9kl5EZf1rz1pCTkRUosaIlIjfE--
-rw-r--r-- 1 root root 12288 2010-08-24 08:46 ECRYPTFS_FNEK_ENCRYPTED.FWbHtjpMW4PshkQYqeqfXg.U0JuQXr1L9kl5XIV47v4Cjghfg43P44xFJ---
-rw-r--r-- 1 root root 12288 2010-08-24 08:53 file3-2.6.36

The contents of the file were encrypted, though.
