[uml-devel] winch_thread : TIOCSCTTY failed on fd 1 err = 1

["Toralf Förster" <toralf.foerster@gmx.de>]

Using Linus' current git tree to bisect a fs/dcache.c issue I realized
this message (newly introduced in one of the last few pulls, meaning
between linux-v3.11-8718 and v3.11-9031-ga22a0fd):


...
Netdevice 0 (72:ef:3d:fd:4a:0b) :
TUN/TAP backend -
winch_thread : TIOCSCTTY failed on fd 1 err = 1
...



Do I have to worry about ?




FWIW I just patched the kernel by this :
