Subject: um: Missing pipe handling
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9fcb663be42e4727c1beabc7c80e2d839199e6b1;p=linux-beck.git

um: Missing pipe handling

UML does not handle sigpipe. As a result when running it under
expect or redirecting the IO from the console to an external program
it will crash if the program stops or exits.
