Subject: [PATCH 11/26] rtlwifi: reduce stack usage for KASAN
When CONFIG_KASAN is set, we use a large amount of stack in the btcoexist code,
presumably due to lots of inlining of functions that each add to the kernel
stack.
net/wireless/realtek/rtlwifi/btcoexist/halbtc8192e2ant.c:3762:1: error: the frame size of 4032 bytes is larger than 3072 bytes
net/wireless/realtek/rtlwifi/btcoexist/halbtc8723b2ant.c:3076:1: error: the frame size of 4104 bytes is larger than 3072 bytes
net/wireless/realtek/rtlwifi/btcoexist/halbtc8821a2ant.c:3740:1: error: the frame size of 3408 bytes is larger than 3072 bytes
I went through these recursively and marked functions as noinline_for_kasan
until no function used more than a kilobyte. While I saw the warning only for
three of the five files, I'm changing all five the same way for consistency.
This should help in case gcc later makes different inlining decisions.
