      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"

      Pull xfs irix ioctl housecleaning from Darrick Wong:
       "Remove the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl families.
      
        This is the second of a series of small pull requests that perform
        some long overdue housecleaning of XFS ioctls. This time, we're
        vacating the implementation of all variants of the ALLOCSP and FREESP
        ioctls, which are holdovers from EFS in Irix, circa 1993. Roughly
        equivalent functionality have been available for both ioctls since
        2.6.25 (April 2008):
      
         - XFS_IOC_FREESP ftruncates a file.
      
         - XFS_IOC_ALLOCSP is the equivalent of fallocate.
      
        As noted in the fix patch for CVE 2021-4155, the ALLOCSP ioctl has
        been serving up stale disk blocks since 2000, and in 21 years
        **nobody** noticed. On those grounds I think it's safe to vacate the
        implementation.
      
        Note that we lose the ability to preallocate and truncate relative to
        the current file position, but as nobody's ever implemented that for
        the VFS, I conclude that it's not in high demand.
      
        Linux has always used fallocate as the space management system call,
        whereas these Irix legacy ioctls only ever worked on XFS, and have
        been the cause of recent stale data disclosure vulnerabilities. As
        equivalent functionality is available elsewhere, remove the code"

        removes the FSSETDM ioctl, which was used to set DMAPI event
        attributes on XFS files. The DMAPI support has never been merged
        upstream and the implementation of FSSETDM itself was removed two
        years ago, so let's withdraw it completely.
