s390/perf: make cf_diag_csd static (06f9895f) · Commits · 戴 / test

Since there is really no reason for cf_diag_csd per cpu variable to be globally visible make it static to avoid the following sparse warning: arch/s390/kernel/perf_cpum_cf_diag.c:37:1: warning: symbol 'cf_diag_csd' was not declared. Should it be static? Signed-off-by:
