Sets the number of hash buckets available for hashing the
in-memory inodes of the specified mount point. If a value
of zero is used, the value selected by the default algorithm
will be displayed in /proc/mounts.
In memory inode hashes have been removed, so this option has
no function as of August 2007. Option is deprecated.
ikeep/noikeep
When inode clusters are emptied of inodes, keep them around
on the disk (ikeep) - this is the traditional XFS behaviour
and is still the default for now. Using the noikeep option,
inode clusters are returned to the free space pool.

inode64
Indicates that XFS is allowed to create inodes at any location
