From 7704182387f7eab6217a587420f8a3b3aa2d17d5 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Fri, 12 Sep 2014 20:19:48 +0800 Subject: [PATCH] f2fs: use nm_i->next_scan_nid as default for next_free_nid Now, if there is no free nid in nm_i->free_nid_list, 0 may be saved into next_free_nid of checkpoint, this may cause useless scanning for next mount. nm_i->next_scan_nid should be a better default value than 0.
