Subject: [PATCH] mac80211: Deinline rate_control_rate_init,
|
|
rate_control_rate_update
|
|
|
|
With this .config: http://busybox.net/~vda/kernel_config,
|
|
after deinlining these functions have sizes and callsite counts
|
|
as follows:
|
|
|
|
rate_control_rate_init: 554 bytes, 8 calls
|
|
rate_control_rate_update: 1596 bytes, 5 calls
|
|
|
|
Total size reduction: about 11 kbytes.
