From 67fce70ba341f772073cac9c3044aa98c69b24fb Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Fri, 22 Jun 2018 16:06:59 +0800 Subject: f2fs: disable f2fs_check_rb_tree_consistence If there is millions of discard entries cached in rb tree, each sanity check of it can cause very long latency as held cmd_lock blocking other lock grabbers. In other aspect, we have enabled the check very long time, as we see, there is no such inconsistent condition caused by bugs. But still we do not choose to kill it directly, instead, adding an flag to disable the check now, if there is related code change, we can reuse it to detect bugs.
