Yes, it is! Compare with fsstress, if we test on filesystems which don't support IOC_ALLOCSP. We have to use "-F" option, but "-F" will disable "fallocate" either, that's not what we want. But fsstress won't fail even if allocsp_f() fails. We can talk about if fsstress need to remove IOC_ALLOCSP. But for fsx, better to disable it by default at least(and use another option to enable it), or remove it as you suggested :) > > Anyway, ALLOCSP was broken for decades and is now gone, so: > Reviewed-by: Darrick J.

Due to XFS_IOC_ALLOCSP is nearly retired from linux xfs, and the ALLOCSP testing in fsx easily trigger errors. So compare with disable it by default, I'd like to remove it entirely. So this patch revert two patches: cd99a499 ("fsx: disable allocsp_calls if -F is specified") a32fb1bb ("fsx: add support for XFS_IOC_ALLOCSP") Signed-off-by: Zorro Lang <zlang@redhat.com> --- Hi, As we talked in: https://lore.kernel.org/fstests/20220330045718.wqrarqorslzaeks5@zlang-mailbox/T/#t We have two choices: 1) Disable ALLOCSP from fsx by default, and give it another option to enable it manually if someone need it. 2) Remove the ALLOCSP support from fsx entirely As Darrick's suggestion, this patch choose the 2nd one. Please review and feel free to tell me if you have other suggestions.
