From 8fc2cb4ba03ee3502ec23de825cd133f5388738f Mon Sep 17 00:00:00 2001 From: Gang He Date: Thu, 5 Apr 2018 16:19:25 -0700 Subject: ocfs2: fix some small problems First, move setting fe_done = 1 in spin lock, avoid bring any potential race condition. Second, tune mlog message level from ERROR to NOTICE, since the message should not belong to error message. Third, tune errno to -EAGAIN when file check queue is full, this errno is more appropriate in the case.
