Tatsuyuki Ishi	41c6b56142	bpf: Replace map types to use &self, remove HashMap::get_mut ... The bpf_map_defs are now wrapped with UnsafeCell, which also happens to provide a cozy way to get a *mut pointer. An UnsafeCell isn't strictly required as the struct fields are practically opaque to us, but using an UnsafeCell follows the general best practices against miscompilation and also prevents some obvious errors. HashMap::get_mut was removed because the idea is completely unsound. Previous users should wrap their data with UnsafeCell instead or use atomics.

Tw	d1b7b024dc	bpf: fix a minor bug due to stackid allocation ... The type casting introduces an allocation, this will cause compiling failure when linking final bpf target. So remove this casting to fix this issue. BTW, the following is the failure I met: = note: 07:24:12 [ERROR] fatal error: "unable to allocate function return #1" PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.
