From a50f6ab3fd31b084b851c5c196db6c900af2c7cc Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 29 Nov 2021 11:21:56 +0100 Subject: [PATCH] xfs: use xfs_direct_write_iomap_ops for DAX zeroing While the buffered write iomap ops do work due to the fact that zeroing never allocates blocks, the DAX zeroing should use the direct ops just like actual DAX I/O.
