It's actually still wrong. This has been broken for
a very long time. It you can fix it, great. Otherwise
this is a useless value, since /proc/*/stat provides
start_code and end_code already.

The statm file is supposed to contain a field known
as "trs" or "trss". This is like rss, but text-only.
Likewise, statm also contains "drs" or "drss" for data.
When you subtract start_code from end_code, you're
generating a value known as "tsiz" (the text size).
The statm file is supposed to supply trs, not tsiz.

Back in the days of a.out, statm also contained lrs
for libraries. ELF broke this.

The statm VM size is supposed to count IO mappings.
So if your X server maps 64 MB of video RAM, then
the statm file should have a value 64 MB larger than
the status file has.

The current 2.6 semantics are purely virtual, so this merely
reimplements those semantics more efficiently. The scheme you
describe would require accounting at the time of pte modification
to implement in a like fashion, which has been rejected.

This would not be difficult to perform additional accounting for.
I'll follow up with that shortly.

Account reserved memory properly as per acahalan's sepecified semantics.

Unrelated fix. Unaccount VM_DONTCOPY vmas properly; the child inherits
the whole of the parent's virtual accounting from the memcpy() in
copy_mm(), but the VM_DONTCOPY check here is where a decision is made
for the child not to inherit the vmas corresponding to some accounted
memory usages. Hence, unaccount them when skipping over them here.

Unrelated improvement (not mandatory or a fix for a bug). Remove the
accounting overhead when CONFIG_PROC_FS is not defined.

Hmmm, why not reject RSS too then? It's the same thing.

If trs and drs and so on were kept, then rss would
just be the sum of them. Per-permission tracking
seems about right:

rss[perms] += change;

(where "perms" is rwx plus shared/private and dirty/clean)

At some point, it would be good to have per-vma rss.
This would be displayed by the pmap command's -x option.
(added to /proc/*/maps right before the filename)

Generally the way these patches have operated is accounting
only the interesting combinations of those with respect to
reporting in the interest of conserving space in the mm. These
have also been combined with various checks on e.g. address
ranges and some special casing of hugetlb. So it's not been
quite as simple as all that.

The code from my 2.6.0-test7-bk1 forward port of the Red Hat patches
for this was as follows:

static inline void vm_account(struct vm_area_struct *vma, pte_t pte,
					unsigned long addr, long adjustment)
{
	struct mm_struct *mm = vma->vm_mm;
	unsigned long pfn;
	struct page *page;

	if (!pte_present(pte))
		return;

	pfn = pte_pfn(pte);
	if (!pfn_valid(pfn))
		goto out;

	page = pfn_to_page(pfn);
	if (PageReserved(page))
		goto out;

	if (vma->vm_flags & VM_EXECUTABLE)
		mm->text += adjustment;
	else if (vma->vm_flags & (VM_STACK_FLAGS & (VM_GROWSUP | VM_GROWSDOWN))) {
		mm->data += adjustment;
		mm->stack += adjustment;
	} else if (addr >= TASK_UNMAPPED_BASE)
		mm->lib += adjustment;
	else
		mm->data += adjustment;

	if (page_mapping(page))
		mm->shared += adjustment;

out:
	if (pte_write(pte))
		mm->dirty += adjustment;

2.6.8.1-mm4

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.8.1/2.6.8.1-mm4/

- Added the kexec code.  Again.  This was in -mm a year or so ago but didn't
  make it.

- This kernel has an x86 patch which alters the copy_*_user() functions so
  they will return -EFAULT on a fault rather than the number of bytes which
  remain to be copied.  This is a bit of an experiment, because this seems to
  be the preferred API for those functions.   It's a see-what-breaks thing.

  And things will break.  If weird behaviour is observed, please revert
  usercopy-return-EFAULT.patch and send a report.

task_vsize() doesn't need mm->mmap_sem for the CONFIG_MMU case; the
semaphore doesn't prevent mm->total_vm from going stale or getting
inconsistent with other numbers regardless. Also, KSTK_EIP() and
KSTK_ESP() don't want or need protection from mm->mmap_sem either. So
this pushes mm->mmap_sem to task_vsize() in the CONFIG_MMU=n task_vsize().

Also, hoist the prototype of task_vsize() into proc_fs.h

The net result of this is a small speedup of procps for CONFIG_MMU.

I'd prefer it if you (and everyone else) could give a meaningful
English-language Subject: to patches, please.

A well-chosen patch Subject: becomes a sort of globally-unique key by which
the patch is tracked - I munge it into a patch filename and it propagates
all the way into bitkeeper.  It can be used for searching email folders,
googling, inter-developer discussion, etc, etc.

Thanks.

Is this better?

Merely removing down_read(&mm->mmap_sem) from task_vsize() is too
half-assed to let stand. The following patch removes the vma iteration
as well as the down_read(&mm->mmap_sem) from both task_mem() and
task_statm() and callers for the CONFIG_MMU=y case in favor of
accounting the various stats reported at the times of vma creation,
destruction, and modification. Unlike the 2.4.x patches of the same
name, this has no per-pte-modification overhead whatsoever.

This patch quashes end user complaints of top(1) being slow as well as
kernel hacker complaints of per-pte accounting overhead simultaneously.

Incremental atop the task_vsize() de-mmap_sem-ification of 2.6.8.1-mm4:

Some kind of brainfart happened here, though it's not visible on the
default display from top(1) etc. This patch fixes up the gibberish I

it from data as per the O(vmas) code beforehand.
