From cd2ee4a30cc0775d8b54e5b958613361a7cacfec Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Thu, 5 May 2005 16:15:32 -0700 Subject: [PATCH] uml: Fix SIGWINCH relaying This makes SIGWINCH work again, and fixes a couple of SIGWINCH-associated crashes. First, the sigio thread disables SIGWINCH because all hell breaks loose if it ever gets one and tries to call the signal handling code. Second, there was a problem with deferencing tty structs after they were freed. The SIGWINCH support for a tty wasn't being turned off or freed after the tty went away.
