From 071401258a580dec2a3e0c2700b7e76f3ed43320 Mon Sep 17 00:00:00 2001 From: Wang Sheng-Hui Date: Fri, 23 Nov 2012 03:03:14 +0000 Subject: Btrfs: do not warn_on io_ctl->cur in io_ctl_map_page io_ctl_map_page is called by many functions in free-space-cache. In most scenarios, the ->cur is not null, e.g. io_ctl_add_entry. I think we'd better remove the warn_on here.
