Subject: [PULL 05/13] linux-user: fix O_NONBLOCK usage for hppa target
Date: Mon, 15 Feb 2021 13:45:11 +0100	[thread overview]
Message-ID: <20210215124519.720265-6-laurent@vivier.eu> (raw)
In-Reply-To: <20210215124519.720265-1-laurent@vivier.eu>

From: Helge Deller <deller@gmx.de>

Historically the parisc linux port tried to be compatible with HP-UX
userspace and as such defined the O_NONBLOCK constant to 0200004 to
emulate separate NDELAY & NONBLOCK values.

Since parisc was the only Linux platform which had two bits set, this
produced various userspace issues. Finally it was decided to drop the
(never completed) HP-UX compatibilty, which is why O_NONBLOCK was
changed upstream to only have one bit set in future with this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=75ae04206a4d0e4f541c1d692b7febd1c0fdb814

This patch simply adjusts the value for qemu-user too.
