Hi Bryan,

Patch descriptions should include _why_ a change is being made,
not just what the change is.

Thanks Randy. I am just confused by the following comments in -mm tree
init/main.c:
---
/* Untouched command line saved by arch-specific code. */
char __initdata boot_command_line[COMMAND_LINE_SIZE];
/* Untouched saved command line (eg. for /proc) */
char *saved_command_line;
---

And you know, in the 2.6.20.x stable kernel init/main.c:
---
/* Untouched command line (eg. for /proc) saved by arch-specific code. */
char saved_command_line[COMMAND_LINE_SIZE];
---

So the patch is to move saved_command_line to boot_command_line in
blackfin arch code. I will resend a new patch about this, because I
forgot to change :-<
---
-	saved_command_line[COMMAND_LINE_SIZE - 1] = 0;
+	boot_command_line[COMMAND_LINE_SIZE - 1] = 0;
---

Did I misunderstand about this? So some other arch (ARM/AVR32 ...)
should be updated, too.

Thanks again Randy.
I will follow the rule.

[PATCH] blackfin arch: use boot_command_line instead of saved_command_line in setup c file

[Wu, Bryan]

[PATCH] blackfin arch
As boot_command_line is added in init/main.c for arch-specific boot
command line, replace old saved_command_line to boot_command_line for
right boot command passing in -mm tree.
