| Subject | [PATCH v5 16/17] xfs: use struct iomap based DAX PMD fault path |
| Date | 2016-10-07 23:20 +0200 |
| Message-ID | <spKIG-69y-19@gated-at.bofh.it> (permalink) |

| Organization | linux.* mail to news gateway |
Switch xfs_filemap_pmd_fault() from using dax_pmd_fault() to the new and
improved dax_iomap_pmd_fault(). Also, now that it has no more users,
remove xfs_get_blocks_dax_fault().
