Hello everyone,

I'd like to request a review to merge these patches into stable releases.

These patches fix race conditions in pending packets from
mac80211_hwsim which cause kernel panic after a device is running for
a few hours. It makes test cases in Android(which uses mac80211_hwsim
for test purposes) flaky, and also, makes Android emulator unstable.

It would be great if these patches could be merged after version 4.19.

If you have further questions, please let me know!

commit cc5250cdb43d444061412df7fae72d2b4acbdf97 wifi: mac80211_hwsim:
use 32-bit skb cookie
commit 58b6259d820d63c2adf1c7541b54cce5a2ae6073 wifi: mac80211_hwsim:
add back erroneously removed cast
commit 4ee186fa7e40ae06ebbfbad77e249e3746e14114 wifi: mac80211_hwsim:
fix race condition in pending packet

Thanks
Jeongik
