This is a v4.14-stable backport of my "Fix DM DAX handling" series which had backport collisions. This series also includes a few patches that were backport dependencies. Changes from the v4.17-stable version: * DAX on raw mode namespace is allowed in this baseline, so we allow it for DM devices as well. This meant dropping the patch "pmem: only set QUEUE_FLAG_DAX for fsdax mode". * Pulled in one additional patch from Mike as a backport dependency. Darrick J. Wong (1): fs: allow per-device dax status checking for filesystems Dave Jiang (1): dax: change bdev_dax_supported() to support boolean returns Mike Snitzer (1): dm: set QUEUE_FLAG_DAX accordingly in dm_table_set_restrictions() Ross Zwisler (2): dax: check for QUEUE_FLAG_DAX in bdev_dax_supported() dm: prevent DAX mounts if not supported drivers/dax/super.c | 42 +++++++++++++++++++++++++----------------- drivers/md/dm-table.c | 9 ++++++--- drivers/md/dm.c | 6 +----- fs/ext2/super.c | 3 +-- fs/ext4/super.c | 3 +-- fs/xfs/xfs_ioctl.c | 3 ++- fs/xfs/xfs_iops.c | 30 +++++++++++++++++++++++++----- fs/xfs/xfs_super.c | 10 ++++++++-- include/linux/dax.h | 11 ++++++----- 9 files changed, 75 insertions(+), 42 deletions(-) -- 2.14.4
