I suspect that problem is that "do_sync" and "do_barriers" in
drivers/md/raid1.c are still 'bool' and should now be 'unsigned long'.

I'm not sure how wide '_Bool' is, but I'm guess it isn't wide enough.

ANSI says:
An object declared as type _Bool is large enough to store the values 0
and 1.

gcc spec doesn't say anything, but:
$ gcc -S -x c -o - -
unsigned long x = sizeof(_Bool);
^D
...
x:
        .quad   1

I.e. sizeof(_Bool) = 1 byte.

Could you please try changing ever 'bool' in that file to 'unsigned long'
and see if that fixes it?

Will do that.

thanks,
