From 0d33aa43516a27d3e47f98d36a1da940fd2a4352 Mon Sep 17 00:00:00 2001 From: Sergey Senozhatsky Date: Sat, 25 Mar 2023 11:46:31 +0900 Subject: [PATCH] zsmalloc: document freeable stats commit 618a8a917dbf5830e2064d2fa0568940eb5d2584 upstream. When freeable class stat was added to classes file (back in 2016) we forgot to update zsmalloc documentation. Fix that.
