Hi, As subject. -d su=2m,sw=1 && -o dax fail -d su=2m,sw=1 && NO dax pass no su mkfs option && -o dax pass no su mkfs option && NO dax pass On latest Linus tree. Reproduce every time. Testing on older kernels are going on to see if it's a regression. Is this failure expected ? Thanks, M # fail with 2m su mkfs option and dax mount option: FSTYP -- xfs (debug) PLATFORM -- Linux/x86_64 7u 5.3.0-rc1-master-ad5e427+ #126 SMP Wed Jul 24 14:46:09 CST 2019 MKFS_OPTIONS -- -f -f -b size=4096 -d su=2m,sw=1 /dev/pmem1 MOUNT_OPTIONS -- -o dax -o context=system_u:object_r:root_t:s0 /dev/pmem1 /test1 xfs/050 4s ...
