Re: [HPDD-discuss] [PATCH 2/11] Staging: lustre: fld: Use kzalloc and kfree
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).
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.
thanks,
julia
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;
}
Bye,
Oleg
