Sadly, from a look at the Fedora CVS, it seems like Fedora 12 is  
shipping with IMA enabled.

By the looks of things, we could change to using filp_open with  
pathnames to open and close cache files (in the same way as we  
currently do on Mac OS X and Solaris). However, filp_open doesn't have  
the support that dentry_open() has for opening files with a specific  
set of credentials. This means that the problems we had recently with  
Apparmour and Selinux crashing us will reappear.

At this point, I'm not sure of what the best course of action is ...
