Hi, this has been previously posted here [1]. Based on the discussion I have dropped "[PATCH 9/9] net, bpf: use kvzalloc helper" and added "[PATCH] xattr: zero out memory copied to userspace in getxattr". I have rebased the series on top of 4.11-rc1. I hope there are no further obstacles to have this merged during this release cycle. Original cover: There are many open coded kmalloc with vmalloc fallback instances in the tree. Most of them are not careful enough or simply do not care about the underlying semantic of the kmalloc/page allocator which means that a) some vmalloc fallbacks are basically unreachable because the kmalloc part will keep retrying until it succeeds b) the page allocator can invoke a really disruptive steps like the OOM killer to move forward which doesn't sound appropriate when we consider that the vmalloc fallback is available. As it can be seen implementing kvmalloc requires quite an intimate knowledge if the page allocator and the memory reclaim internals which strongly suggests that a helper should be implemented in the memory subsystem proper. Most callers, I could find, have been converted to use the helper instead. This is patch 6. There are some more relying on __GFP_REPEAT in the networking stack which I have converted as well and Eric Dumazet was not opposed [2] to convert them as well.
