From c192f7a4779559dddeb8c03de2b6ef499115c938 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Wed, 22 Feb 2017 17:10:18 -0800 Subject: [PATCH] f2fs: find data segments across all the types Previously, if type is CURSEG_HOT_DATA, we only check CURSEG_HOT_DATA only. This patch fixes to search all the different types for SSR.
