drivers/staging/lustre/lustre/fid/lproc_fid.c: In function 'ldebugfs_fid_write_common': drivers/staging/lustre/lustre/fid/lproc_fid.c:67:6: warning: variable 'rc' set but not used [-Wunused-but-set-variable] int rc; We fix it by *using* the return code to help bulletproof it. It says it's test code - it should be *more* bulletproof than production, not less.
