Noisier debugging of unexpected mid cancellation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Have been trying to debug xfstest 28 warnings (unexpected cancellation
of mid "CIFS VFS: Close unmatched open") so wanted to make this
earlier (FYI level) message noisier and add which command is causing
it (in this case open)

Thanks,
