From 94f1b99298bd5d82b855664f721a6f543617df4e Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 15 Nov 2017 17:35:02 -0800 Subject: nilfs2: use pagevec_lookup_range_tag() We want only pages from given range in nilfs_lookup_dirty_data_buffers(). Use pagevec_lookup_range_tag() instead of pagevec_lookup_tag() and remove unnecessary code.
