[PATCH 5/5] xfs: remove never-implemented scrub declarations

[Zizhi Wo]

From: Zizhi Wo <wozizhi@xxxxxxxxxx>

Commit dcb660f9222f ("xfs: probe the scrub ioctl") added a declaration for
xfs_scrub_tester() (now xchk_tester) as a placeholder in 2017, but the
function was never implemented.

Likewise commit 99d9d8d05da2 ("xfs: scrub inode block mappings") declared
xfs_scrub_setup_inode_bmap_data() (now xchk_setup_inode_bmap_data) in 2017,
which was never implemented either; the scrub ioctl table uses
xchk_setup_inode_bmap() for BMBTD/BMBTA/BMBTC checks.

Finally, the !CONFIG_XFS_ONLINE_REPAIR stub of xrep_tempfile_iolock_both()
added by commit 84c14ee39dd3 ("xfs: create temporary files and directories
for online repair") has no callers.

Remove these dead declarations and the unused stub.

Note: if any of them are intended to be implemented in the future, please
just ignore the corresponding patch. I'm only sending these because they
have been sitting unimplemented since 2017.
