H A Dinode.c64ee4808 Thu Jul 19 03:47:54 CDT 2007 Michael Halcrow <mhalcrow@us.ibm.com> eCryptfs: ecryptfs_setattr() bugfix

There is another bug recently introduced into the ecryptfs_setattr()
function in 2.6.22. eCryptfs will attempt to treat special files like
regular eCryptfs files on chmod, chown, and so forth. This leads to a NULL
pointer dereference. This patch validates that the file is a regular file
before proceeding with operations related to the inode's crypt_stat.

Thanks to Ryusuke Konishi for finding this bug and suggesting the fix.
