Please change this to be a static branch.

Will do. I renamed memalloc_socks to sk_memalloc_socks, made it a int as
atomics are unnecessary and I check it directly in a branch instead of a
static inline. It should be relatively easy for the branch predictor.

No branch predictor can beat an unconditional branch :-)
