[lustre-devel] [PATCH 01/12] lustre: llite: move CONFIG_SECURITY handling to llite_internal.h

[James Simmons]

For the linux kernel its recommended to keep CONFIG_* wrapped code
in a header file instead of the source files to avoid making the
code more difficulty to read. Move CONFIG_SECURITY wrapped code
to llite_internal.h in this case.
