From: Darrick J. Wong <djwong@kernel.org>

The xfs_eofblocks structure is no longer well-named -- nowadays it
provides optional filtering criteria to any walk of the incore inode
cache.  Only one of the cache walk goals has anything to do with
clearing of speculative post-EOF preallocations, so change the name to
be more appropriate.

Ah, ok, that's why the flags were encoded to have the same values as
the user API - it's just a straight value copy of the field.

Hmmmm. What happens in future if we've added new internal flags and
then add a new API flag and they overlap in value? That seems like
a bit of landmine?

Otherwise the change looks good.

Cheers,

Dave.

As mentioned in the previous reply, I'll separate them completely then.

	dst->icw_flags = 0;
	if (src->eof_flags & XFS_EOF_FLAGS_SYNC)
		dst->icw_flags |= XFS_ICWALK_FLAG_SYNC;
	if (src->eof_flags & XFS_EOF_FLAGS_UID)
		dst->icw_flags |= XFS_ICWALK_FLAG_UID;

	if (src->eof_flags & XFS_EOF_FLAGS_MINFILESIZE)
