winch_thread : TIOCSCTTY failed on fd 1 err = 1
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 :
kernel/exit.c +1 -1
