Hi,

i have downloaded linux kernel 2.4.21 and gcov patch for the same version.
i applied patch. I am sure,there is no error in applying patch.

i compiled the kernel and i booted with new gcov image.
but i am not able to load any other modules(any usb related modules only i
checked), because of unresolved symbol " __b_init_func"
this symbol __b_init_func is introduced by gcov-2.4.21 patch

while installing gcov-proc.o or any other modules, i am getting this
following error.
/lib/modules/2.4.21-gcov/kernel/drivers/gcov/gcov-proc.o: unresolved symbol
__bb_init_func
/lib/modules/2.4.21-gcov/kernel/drivers/gcov/gcov- proc.o: insmod
/lib/modules/2.4.21-gcov/kernel/drivers/gcov/gcov-proc.o failed
/lib/modules/2.4.21-gcov/kernel/drivers/gcov/gcov-proc.o: insmod gcov-proc
failed

i did grep on System.map file, it is giving following output
c013b2c0 T __bb_init_func
c0495812 R __kstrtab___bb_init_func
c04a2638 R __ksymtab___bb_init_func

and

i did "cat  /proc/ksym | grep __b_init " , it is giving following output
c013b2c0 __bb_init_func_Re16fd186

i am facing this problem on gcov-2.4.20.patch also

thanks
Ashok
