From 9006f2c93fe5cc450bc0d3a4924b46393f165b4a Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Tue, 1 Dec 2015 11:47:33 +0800 Subject: f2fs: kill f2fs_drop_largest_extent For direct IO, f2fs only allocate new address for the block which is not exist in the disk before, its mapping info should not exist in extent cache previously, so here we do not need to call f2fs_drop_largest_extent to drop related cache. Due to no more callers for f2fs_drop_largest_extent now, kill it.
