Date: Wed, 16 Dec 2020 12:25:13 +0000 From: Colin King <colin.king@...onical.com> To: Trond Myklebust <trond.myklebust@...merspace.com>, Anna Schumaker <anna.schumaker@...app.com>, Frank van der Linden <fllinden@...zon.com>, linux-nfs@...r.kernel.org Cc: kernel-janitors@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH][next] NFSv4.2: fix error return on memory allocation failure From: Colin Ian King <colin.king@...onical.com> Currently when an alloc_page fails the error return is not set in variable err and a garbage initialized value is returned. Fix this by setting err to -ENOMEM before taking the error return path.
