Hi Zorro, Can we assume all the FIEMAP tests need this check first? If so, there are some others need the same patch. I.e. [yoyang@yoyang-vm xfstests-dev]$ grep url .git/config url = git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git [yoyang@yoyang-vm xfstests-dev]$ git pl Already up to date. [yoyang@yoyang-vm xfstests-dev]$ git grep _begin_fstest tests/ | grep fiemap | wc -l 101 [yoyang@yoyang-vm xfstests-dev]$ git grep _require_xfs_io_command tests/ | grep fiemap | wc -l 86 [yoyang@yoyang-vm xfstests-dev]$ Best Regards, Yongcheng
