Helge Deller 15ad7cdcfd [PATCH] struct seq_operations and struct file_operations constification
- move some file_operations structs into the .rodata section

 - move static strings from policy_types[] array into the .rodata section

 - fix generic seq_operations usages, so that those structs may be defined
   as "const" as well

[akpm@osdl.org: couple of fixes]
