From 5df1d4123d53261d9d71c7d237d0f165add7ce72 Mon Sep 17 00:00:00 2001 From: "zhangyi (F)" Date: Thu, 24 Sep 2020 15:33:35 +0800 Subject: ext4: introduce ext4_sb_breadahead_unmovable() to replace sb_breadahead_unmovable() If we readahead inode tables in __ext4_get_inode_loc(), it may bypass buffer_write_io_error() check, so introduce ext4_sb_breadahead_unmovable() to handle this special case. This patch also replace sb_breadahead_unmovable() in ext4_fill_super() for the sake of unification.
