From bd5c4facf59648581d2f1692dad7b107bf429954 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Wed, 21 Mar 2018 12:49:29 -0400 Subject: Fix slab name "biovec-(1<<(21-12))" I'm getting a slab named "biovec-(1<<(21-12))". It is caused by unintended expansion of the macro BIO_MAX_PAGES. This patch renames it to biovec-max.
