Hi -
Is there a way to get char * initialized data to go into the init
data section?
For example, in the following I want init_foobar and its associated
text strings to go into the init data section, not just the pointers
in init_foobar:
[patman@elm3a50 bleed-2.5]$ more initdata.c
#include <linux/init.h>
/*
* This only puts the pointer in .init.data.
*/
char *init_foobar[] __initdata = {
"AAAAtextAAAAtextAAAAtext-morea",
"AAAA",
"AAAA",
};
/*
* Following is OK, but wastes some space (on disk) and needs one extra byte
* for the '\0'. Worse, the second entry below is not '\0' terminated and gets
* no compilation warning :(
*/
char init_foobar2[][31] __initdata = {
"BBBBtextBBBBtextBBBBtext-morea",
"BBBBtextBBBBtextBBBBtext-morebc",
"BBBB",
"BBBB",
};
char *regular_foobar[] = {
"CCCCtextCCCCtextCCCCtext-morea",
"CCCCtextCCCCtextCCCCtext-moreb",
"CCCC",
};
[patman@elm3a50 bleed-2.5]$ objdump -s initdata.o
initdata.o: file format elf32-i386
