RE: [PATCH] [media] v4l: vb2-memops: use vma slab when vma allocation

Hans, I didn't notice that vb2_put_vma is exported because I don't build modules. I am sorry about bothering you. Mauro, I think it is better to drop my patch out from your tree because I don't think it is not worth to export vm_area_cache_p to use it in vb2_put_vma. Regards, KyongHo -Origi

Re: [PATCH] [media] v4l: vb2-memops: use vma slab when vma allocation

Mauro, Please revert this patch: vm_area_cachep is not exported, so you cannot use this in a module. Cho KyongHo, if you believe that vm_area_cachep should be exported so it can be used here, then please make a patch for that. For the time being though, this patch should be reverted. This patch

[PATCH] [media] v4l: vb2-memops: use vma slab when vma allocation

The slab for vm_area_struct which is vm_area_cachep is already prepared for the general use. Instead of kmalloc() for the vma copy for userptr, allocation from vm_area_cachep is more beneficial. CC: Mauro Carvalho Chehab CC: Hans Verkuil CC: Laurent Pinchart Signed-off-by: Cho KyongHo --- dri
