From 37e67d15950a52b096601e98081abc2b17bd3a2b Mon Sep 17 00:00:00 2001 From: Chris Johns Date: Mon, 20 Nov 2023 12:04:58 +1100 Subject: Reclaim _REENT_MP_P5S in _reclaim_reent The _REENT_MP_P5S blocks are allocated using Balloc via i2b and linked in the pow5mult call. As a result these blocks are not on the freelist managed by the Bfree call. This change fixes a memory leak in threads that clean up using _reclaim_reent.
