Subject: [PATCH AUTOSEL 5.1 025/375] orangefs: truncate before updating size
Date: Wed, 22 May 2019 15:15:25 -0400	[thread overview]
Message-ID: <20190522192115.22666-25-sashal@kernel.org> (raw)
In-Reply-To: <20190522192115.22666-1-sashal@kernel.org>

From: Martin Brandenburg <martin@omnibond.com>

[ Upstream commit 33713cd09ccdc1e01b10d0782ae60200d4989553 ]

Otherwise we race with orangefs_writepage/orangefs_writepages
which and does not expect i_size < page_offset.

Fixes xfstests generic/129.
