From 64671bafbdd984535aa382bccadd91fbe7be0e80 Mon Sep 17 00:00:00 2001 From: Eryu Guan Date: Mon, 18 Sep 2017 11:38:58 -0700 Subject: [PATCH] xfs: kill meaningless variable 'zero' In xfs_file_aio_write_checks(), variable 'zero' is there only to satisfy xfs_zero_eof(), the result of it is ignored. Now, with iomap_zero_range() based xfs_zero_eof(), we can safely pass NULL as the last param of it and kill 'zero'.
