[PATCH] fsx: remove XFS_IOC_ALLOCSP operation entirely

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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")

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.

Thanks,
Zorro
