I cannot find a time where the function was not named this.

uma: Permit specifying max of cache line and some custom alignment2023-12-21T13:40:09ZOlivier Certnerolce.freebsd@certner.fr2023-10-13T15:05:34Zurn:sha1:6e4b7753610d2594740d73120fe6251ce7f66a61
To be used for structures for which we want to enforce that pointers to
them have some number of lower bits always set to 0, while still
ensuring we benefit from cache line alignment to avoid false sharing
between structures and fields within the structures (provided they are
properly ordered).
First candidate consumer that comes to mind is 'struct thread', see next
commit.

uma: New check_align_mask(): Validate alignments (INVARIANTS)2023-12-21T13:40:09ZOlivier Certnerolce.freebsd@certner.fr2023-10-13T14:09:51Zurn:sha1:27199e55a4d568659d3a4b9985e736e8e5ee3dfe
New function check_align_mask() asserts (under INVARIANTS) that the mask
fits in a (signed) integer (see the comment) and that the corresponding
alignment is a power of two.
Use check_align_mask() in uma_set_align_mask() and also in uma_zcreate()
to replace the KASSERT() there (that was checking only for a power of
2).
