将 nvmain 补丁应用到 gem5 目录时出现错误：
$ hg qpush
applying nvmain2-gem5-11688+
patch failed, unable to continue (try -v)
patch failed, rejects left in working directory
errors during apply, please fix and qrefresh nvmain2-gem5-11688+
我尝试删除更新它的补丁并重新应用，但在应用时遇到相同的错误：
$ hg qpop -a
popping nvmain2-gem5-11688+
patch queue now empty
$ hg qimport -f ~/nvmain/patches/gem5/nvmain2-gem5-11688+
adding nvmain2-gem5-11688+ to series file
