#     Pull more xfs irix ioctl housecleaning from Darrick Wong:
#      "Withdraw the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl definitions.
#     
#       This is the third and final of a series of small pull requests that
#       perform some long overdue housecleaning of XFS ioctls. This time,
#       we're withdrawing all variants of the ALLOCSP and FREESP ioctls from
#       XFS' userspace API. This might be a little premature since we've only
#       just removed the functionality, but as I pointed out in the last pull
#       request, nobody (including fstests) noticed that it was broken for 20
#       years.
#     
#       In response to the patch, we received a single comment from someone
#       who stated that they 'augment' the ioctl for their own purposes, but
#       otherwise acquiesced to the withdrawal. I still want to try to clobber
#       these old ioctl definitions in 5.17.
#     
#       So remove the header definitions for these ioctls. The just-removed
#       implementation has allowed callers to read stale disk contents for
#       more than **21 years** and nobody noticed or complained, which implies
#       a lack of users aside from exploit programs"
