[merged] sysctl-remove-struct-file-argument-of-proc_handler.patch removed from -mm tree

[akpm@xxxxxxxxxxxxxxxxxxxx]

The patch titled
     sysctl: remove "struct file *" argument of ->proc_handler
has been removed from the -mm tree.  Its filename was
     sysctl-remove-struct-file-argument-of-proc_handler.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

------------------------------------------------------
Subject: sysctl: remove "struct file *" argument of ->proc_handler
From: Alexey Dobriyan <adobriyan@xxxxxxxxx>

It's unused.

It isn't needed -- read or write flag is already passed and sysctl
shouldn't care about the rest.

It _was_ used in two places at arch/frv for some reason.
