your change is now upstream:
commit 77b14db502cb85a031fe8fde6c85d52f3e0acb63
Author: Eric W. Biederman <ebiederm@xmission.com>
Date: Wed Feb 14 00:34:12 2007 -0800
but it broke the latency tracer in -rt which uses create_proc_entry() to
attach a custom handler to value changes in preempt_max_latency:
#define PROCNAME_PML "sys/kernel/preempt_max_latency"
static __init int latency_fs_init(void)
{
struct proc_dir_entry *entry;
if (!(entry = create_proc_entry(PROCNAME_PML, 0644, NULL)))
printk("latency_fs_init(): can't create %s\n", PROCNAME_PML);
with your change that broke because beyond /proc/sys/ there are no real
proc entries anymore, there's no de->subdir directory for
xlate_proc_name() to find. While the latency tracer isnt upstream, this
change in semantics does not seem to be intended (the changelog is
certainly silent about it).
