Subject: [GIT PULL] ktest.pl: Updates for 6.3


Linus,

Updates to ktest.pl:

- Fix three instances that the tty is not given back to the console on exit.
  Forcing the user to do a "reset" to get the console back.

- Fix the console monitor to not hang when too much data is given by the ssh
  output.

Note, these were all fixes, but I like to run them internally for a bit
before pushing.

Please pull the latest ktest-v6.3 tree, which can be found at:
