Sorry if what I said was unclear.

Since I just did not a good reason to put
"static ssize_t" in the previous line,
I meant like follows:


[Before]
static ssize_t
ikheaders_read_current(struct file *file, char __user *buf,
                       size_t len, loff_t *offset)



[After]
static ssize_t ikheaders_read_current(struct file *file, char __user *buf,
                                      size_t len, loff_t *offset)


(takes 74-cols.)


(I am sending this from Gmail, so I am not sure
how it will look like from you...)


Anyway, it is super-bikeshedding stuff.
It is OK as-is.
