The patch titled
proc: Kill proc_mem_inode_operations
has been removed from the -mm tree. Its filename is
proc-kill-proc_mem_inode_operations.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: proc: Kill proc_mem_inode_operations
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
The inode operations only exist to support the proc_permission function.
Currently mem_read and mem_write have all the same permission checks as
ptrace. The fs check makes no sense in this context, and we can trivially get
around it by calling ptrace.
So simply the code by killing the strange weird case.
