What happens to string deduplication when one string is in an init function and the same string is also used in a non-init function in the same compilation unit? foo.c __init void initfunc(void) { pr_info("%s: I'm here\n", __func__); } void runtimefunc(void) { pr_info("I'm here: %s\n", __func__); } In what section does the string "I'm here: %s\n" get placed or does it get placed into multiple sections? -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
