From: Johannes Berg Date: Mon, 20 Jan 2014 23:32:52 +0000 (+0100) Subject: mac80211: minstrel_ht: sample_table can be __read_mostly X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6e1a73b66bdf41765e762eda0f4ecb7d987ea57;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git mac80211: minstrel_ht: sample_table can be __read_mostly The sample table is initialized only once at module start, so is really __read_mostly. Additionally, the code to init it can be marked __init since it will never be needed again, it is likely automatically inlined into the __init function already by the compiler, so this doesn't really make a difference.
