[lustre-devel] [PATCH 05/10] lustre: don't declare extern variables in C files.

[James Simmons <jsimmons@infradead.org>]

From: NeilBrown <neilb@suse.com>

'extern' declarations should only appear in .h files.
All these names are declared in .h files as needed,
and these duplicate declarations in .c files can
be removed.
