[uml-devel] Testing needed for terminal handling patches

[Jeff Dike <jdike@addtoit.com>]

I've posted a set of patches that fiddle with UML's handling of terminal modes
to http://user-mode-linux.sourceforge.net/patches.html

I'd like people to try them out and report bad experiences, especially if you
saw the 'netdevice 0' hang or stairstepping output during boot.  They are the
catch-eintr, bb-raw, and clean-raw patches.

In particular, I removed the complain argument to raw, which means that it
will always complain if something failed.  The reason it was there in the
first place is that a long, long time ago, in a universe far, far away, I
saw a failure there on stdout call printk, which would recurse through the
same code, causing the same failure, reporting it through printk again, ad
infinitum.  I'm curious as to whether this infinite recursion was sparked
by an EINTR or something else.

Also, TCSACRAIN is always used instead of TCSANOW.  I don't see any reason
that I need NOW instead of DRAIN.
