If you're going to do this cleanup, make the comment in line 84 grammatical:

/* Used for retrieving partial slabs, etc. */

Then change lines 87 and 88 to remove the space between "meta" and "data" as the
word is "metadata" (as can be seen at line 102) and remove the period at the end
of the comment on line 89 ("Free pointer offset.")

You might also want to change lines 125-127 to be a single line comment:

/* Defragmentation by allocating from a remote node */

so the commenting style is consistent throughout.
