From: Robert P. J. Day <rpjday@xxxxxxxxxxxxxx>
Correct the regular expression in scripts/headers_check.pl to include '_'
as a valid character in the class; otherwise, the check will report a
"leaked" symbol of CONFIG_A_B_C as merely CONFIG_A.
This patch will make no difference whatsoever in the current kernel tree
as the call to the perl routine that does that check is currently
commented out:
&check_include();
&check_asm_types();
&check_sizetypes();
&check_prototypes();
# Dropped for now. Too much noise &check_config();
However, I noticed that problem when I was building the yum downloadable
kernel source rpm for fedora 11 (beta), which *does* run that check, and
that's where the problem became obvious.
