OK, He Zhe, you are almost there.
Let's do the series the following way:
- four patches
- each change goes into a separate patch
- the first two patches Cc stable
patch #0 Cc stable
---
unsigned int size;
if (!str)
return -EINVAL;
size = memparse(str, &str);
---
patch #1 Cc stable
---
len = sprintf(text,
"** %llu printk messages dropped **\n",
log_first_seq - console_seq);
---
=====================================================================
patch #2
---
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
---
patch #3
---
if (size > UINT_MAX) {
size = UINT_MAX;
pr_err("log_buf over 4G is not supported.\n");
}
...
---
-ss
