Error building mvfs

Error building mvfs

I am trying to build mvfs so that I can run IBM Rational ClearCase on a
CentOS 6.4 machine. I have all the dependencies installed so I cd to the
mvfs_src folder and get the following error while running make:
/var/adm/rational/clearcase/mvfs/mvfs_src/mvfs_linux_mvops.c: In function
'mvop_linux_open_kernel':
/var/adm/rational/clearcase/mvfs/mvfs_src/mvfs_linux_mvops.c:1454: error:
implicit declaration of function 'get_empty_filp'
cc1: warnings being treated as errors
/var/adm/rational/clearcase/mvfs/mvfs_src/mvfs_linux_mvops.c:1454: error:

make[2]: ***

make[1]: Leaving directory `/usr/src/kernels/2.6.32-358.14.1.el6.x86_64'
make: *** [all] Error 2
How do I fix this?
