Replace OBD_ALLOC, OBD_ALLOC_WAIT, OBD_ALLOC_PTR, and OBD_ALLOC_PTR_WAIT by
kalloc/kcalloc, and OBD_FREE and OBD_FREE_PTR by kfree. The complete
semantic patch that makes these changes is as follows:

Replace OBD_ALLOC, OBD_ALLOC_WAIT, OBD_ALLOC_PTR, and OBD_ALLOC_PTR_WAIT by
kalloc/kcalloc, and OBD_FREE and OBD_FREE_PTR by kfree.

Replace OBD_ALLOC, OBD_ALLOC_WAIT, OBD_ALLOC_PTR, and OBD_ALLOC_PTR_WAIT by
kalloc/kcalloc, and OBD_FREE and OBD_FREE_PTR by kfree.

A simple replace will not work. The OBD_ALLOC and OBD_FREE functions allocate memory
anywhere from one page to 4MB in size. You can't use kmalloc for the 4MB allocations.
Currently lustre uses a 4 page water mark to determine if we allocate using vmalloc. Even
using kmalloc for 4 pages has shown high failure rates on some systems. It gets even more
messy with 64K page systems like ppc64 boxes. Now I'm not suggesting to port the larger
allocations to vmalloc either since issues have been founded with using vmalloc. For example
when using large stripe count files the MDS rpc generated crosses the 4 page line and vmalloc
is used. Using vmalloc caused a global spinlock to be taken which causes meta data operations
to serialized on the MDS servers.

It's not the LARGE functions that do the switching? For example OBD_ALLOC
ends up at __OBD_MALLOC_VERBOSE, which as far as I can see calls kmalloc
(with __GFP_ZERO, and hance the use of kzalloc).

OBD_FREE() just calls kfree(), it does not allocate any memory, so that
replacement is always ok.

hi Julia,
your patch seems fine.
I tried to understand the code and it seems that much of it
can be simplified by using already available functions.
I have added some comments but i am not sure what to make of it.

perhaps this can be merged.

This is true. We have OBD_ALLOC that is straight kmalloc and then we have OBD_ALLOC_LARGE
that depends on allocation size whenever it's kmalloc or vmalloc.
Similarly we have OBD_FREE and OBD_FREE_LARGE (This one could be converted straight into kvfree).
I think the patches look fine.

We are hopefully going to get rid of OBD_ALLOC_LARGE() as well, though.
It's simple enough to write a function:
void *obd_zalloc(size_t size)
{
if (size > 4 * PAGE_CACHE_SIZE)
return vzalloc(size);
else
return kmalloc(size, GFP_NOFS);
}
Except, huh? Shouldn't we be using GFP_NOFS for the vzalloc() side?
There was some discussion of that GFP_NOFS was a bit buggy back in 2010
(http://marc.info/?l=linux-mm&m=128942194520631&w=4) but the current
lustre code doesn't try to pass GFP_NOFS.
Then it's simple enough to change OBD_FREE_LARGE() to kvfree().
Also it's weird that only the lustre people have thought of this trick
to allocate big chunks of RAM and no one else has. What would happen if
we just change vmalloc() so it worked this way for everyone?
regards,
dan carpenter

kzalloc here too. Except e also want to have locality of allocations.

The patch I submitted was rejected, or so I think to remember, because we use __vmalloc_node
or something and it's not an exported symbol.

We are certainly not alone.
I saw this in a few other pieces of code.
void *ext4_kvmalloc(size_t size, gfp_t flags)
{
void *ret;
ret = kmalloc(size, flags | __GFP_NOWARN);
if (!ret)
ret = __vmalloc(size, flags, PAGE_KERNEL);
return ret;
}
or kmem_zalloc_large in xfs.
The difference at hand is that we pessimistically assume anything over certain threshold would
fail in kmalloc anyway and others actually do try kmalloc and only switch to vmalloc if kmaloc failed.
Considerign how expensive (and unsafe) vmalloc is, there might be some benefit to converting to their
way of doing things too.

Yes the LARGE functions do the switching. I was expecting also patches to remove the
OBD_ALLOC_LARGE functions as well which is not the case here. I do have one question still. The
macro __OBD_MALLOC_VERBOSE allowed the ability to simulate memory allocation failures at
a certain percentage rate. Does something exist in the kernel to duplicate that functionality?
Once these macros are gone we lose the ability to simulate high memory allocation failures.

The version in the upstream client is out of date. The current macro in the Intel master
Branch is:
#define __OBD_VMALLOC_VERBOSE(ptr, cptab, cpt, size) \
do { \
(ptr) = cptab == NULL ? \
__vmalloc(size, GFP_NOFS | __GFP_HIGHMEM | __GFP_ZERO, \
PAGE_KERNEL) : \
cfs_cpt_vzalloc(cptab, cpt, size); \
if (unlikely((ptr) == NULL)) { \
CERROR("vmalloc of '" #ptr "' (%d bytes) failed\n", \
(int)(size)); \
CERROR(LPU64" total bytes allocated by Lustre, %d by LNET\n", \
obd_memory_sum(), atomic_read(&libcfs_kmemory)); \

OBD_ALLOC_POST(ptr, size, "vmalloced"); \

Yes, no need for lustre to duplicate yet-another-thing the kernel
already provides :)

Yes, there are things like https://lkml.org/lkml/2014/12/25/64
So I think the API is even riher compared to what our old wrapper code was able to do.

Please sync with the kernel tree very soon, or I'm just going to delete
this whole thing. This is getting _really_ frustrating.

The patch was submitted.
But it depends on a symbol that's not exported.
I was not able to change that.

But you were given a hint on how to change that :)
Anyway, I'd recommend switching to what ext4 and xfs does, as you point
out in another email in this thread, it looks a lot better overall.

Well, the hint amounted to "don't do vmalloc if you cannot live with the
GFP_KERNEL" allocations.
In any case once we unroll the OBD_ALLOC* (esp. the _LARGE ones), it should be possible
to go through those cases and adjust GFP flags to less restrictive where possible
(right now our macro is way too rigid and does not take gfp flags at all).
> Anyway, I'd recommend switching to what ext4 and xfs does, as you point
> out in another email in this thread, it looks a lot better overall.
Yes, I imagine Julia will include that as the new lustre_kvzalloc() define
to be used in all OBD_ALLOC_LARGE instances.
I can provide the desired code if necessary (it's actually a bit less than trivial
because in some cases we also have that numa-aware node thing).
though if we are ok to review that later, then almost a copy of ext4 one would do like this:
void *lustre_kvzalloc(size_t size, gfp_t flags)
{
void *ret;
ret = kzalloc(size, flags | __GFP_NOWARN);
if (!ret)
ret = __vmalloc(size, flags | __GFP_ZERO, PAGE_KERNEL);
return ret;
}

Oleg

The reason for this is that libcfs was written 10+ years ago which was before linux had such nice
features. At that time it was needed to fill the gaps missing which is no longer the case. Libcfs is
really showing its age :-)

Oleg,
If you could send a patch with the proper definition, that would be very
helpful, thanks. When that is in place, I can update the uses.

Which email is that?
I only see where David says to implement vmalloc_node_gfp() and the talk
was about if that makes sense from a style perspective and then dies.
Anyway, this only seems to affect ptlrpc_alloc_rqbd() since I think
that's the only place which calls OBD_CPT_ALLOC_PTR(). The rest can use
__vmalloc().
