From: Eric Sandeen <sandeen@xxxxxxxxxx> The "maxpct" section of the mkfs.xfs manpage has a gratuitous and incorrect description of the default inode allocator mode. inode64 has been the default since 2012, as of 08bf540412ed xfs: make inode64 as the default allocation mode so the description is wrong. In addition, imaxpct is only tangentially related to inode allocator behavior, so this section of the man page is really the wrong place for discussion.
