Hi Al,

This patch fixes a regression.  Without it, you can't mount a file
system with i_version.  This obviously affects IMA.  Could you pick up
this patch and forward it to Linus please?

Commit dd924ea17c0c "vfs: fix mounting a filesystem with i_version"
can be found in my git repo.

thanks,

Mimi
