From d3b6f23f71670007817a5d59f3fbafab2b794e8c Mon Sep 17 00:00:00 2001 From: Ritesh Harjani Date: Fri, 28 Feb 2020 14:56:58 +0530 Subject: ext4: move ext4_fiemap to use iomap framework This patch moves ext4_fiemap to use iomap framework. For xattr a new 'ext4_iomap_xattr_ops' is added. Reported-by: kbuild test robot Reviewed-by: Jan Kara Reviewed-by: Darrick J.

It's also less racy to set all of the error information all at once. (Also, as a bonus, it shrinks code size slightly.)
