Hi, FIBMAP ioctl call to file in pmem dax mountpoint, both xfs and ext4, starts to fail on v4.17-rc1 Linus tree.
+fibmap: Invalid argument Pass on v4.16. Pass on non-dax mountpoint. We got these in v4.17-rc1: 6e2608d xfs, dax: introduce xfs_dax_aops fb094c9 ext2, dax: introduce ext2_dax_aops 5f0663b ext4, dax: introduce ext4_dax_aops And we don't have ->bmap call in these aops, which may lead to the ioctl call failure. Do we have any plan of adding/supporting it ? xfstests generic/223 covers this issue. If we are not going to support this call for dax, we need to fix the testcase.
