Here are some Warning got when compiling Linux 2.6.65 (devfs not configured)
with the latest gcc-3.4 CVS :
include/linux/devfs_fs_kernel.h: In function `devfs_remove':
include/linux/devfs_fs_kernel.h:101: warning: varargs function cannot be
inline
Possible Fix :
Replace inline-func with macro

I think the inline-attribute should be simply removed to quiet this Warning.
---arch/i386/kernel/ptrace.c: In function `sys_ptrace': warning: `__pu_err' might be used uninitialized in this function
This comes from include/asm-i386
> #define __put_user_nocheck(x,ptr,size) \ > ({ \ > long __pu_err; \ > __put_user_size((x),(ptr),(size),__pu_err,-EFAULT); \ > __pu_err; \ > })
__pu_err is shurely not initialized, but migth this be intentionally ?
---kernel/fork.c: In function `copy_fs': kernel/fork.c:569: warning: function cannot be inline kernel/fork.c: In function `copy_process': kernel/fork.c:569: warning: can't inline call to `copy_fs' kernel/fork.c:882: warning: called from here
I dont understand WHY copy_fs cannont be inlined ...
kernel/posix-timers.c: In function `unlock_timer': kernel/posix-timers.c:564: warning: function cannot be inline
ditto
---kernel/suspend.c: In function `freeze_processes': kernel/suspend.c:228: warning: comparison of distinct pointer types lacks a cast
---drivers/char/vt.c:2457: warning: `return' with a value, in function returning void drivers/char/vt.c:2497: warning: initialization from incompatible pointer type
I think these Warnings appear as con_init is declared as static void __init con_init(void); but typedef int (*initcall_t)(void); suggests that it migth better be static int __init con_init(void) ??
