Currently this does not work for guards +in the "#if defined()" style, which may be needed for non-trivial +cases. + +This patch adds similar logic so that the _UAPI prefix is also +stripped from guard directives written using "#if defined()" etc. + +This is not completely foolproof, but will work for simple cases of +using #if defined() to guard against inappropriate header inclusion. + +Signed-off-by: Dave Martin <Dave.Martin@arm.com> +Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> + +Upstream-Status: Submitted [https://www.spinics.net/lists/arm-kernel/msg694800.html] +--- + scripts/headers_install.sh | 1 + + 1 file changed, 1 insertion(+) + +Index: linux-5.4/scripts/headers_install.sh +=================================================================== +--- linux-5.4.orig/scripts/headers_install.sh ++++ linux-5.4/scripts/headers_install.sh +@@ -36,6 +36,7 @@ + s/(^|[^a-zA-Z0-9])__packed([^a-zA-Z0-9_]|$)/\1__attribute__((packed))\2/g + s/(^|[[:space:](])(inline|asm|volatile)([[:space:](]|$)/\1__\2__\3/g + s@#(ifndef|define|endif[[:space:]]*/[*])[[:space:]]*_UAPI@#\1 @ ++ :1;s/(#(if|elif)(.*[^A-Za-z0-9_])defined\([[:space:]]*)_UAPI/\1/;t1 + ' $INFILE > $TMPFILE || exit 1 + + scripts/unifdef -U__KERNEL__ -D__EXPORTED_HEADERS__ $TMPFILE > $OUTFILE |
