Subject: [PATCH AUTOSEL 5.15 04/65] UNRPC: Return specific error code on kmalloc failure
Date: Tue, 16 Nov 2021 14:03:24 -0500	[thread overview]
Message-ID: <20211116190443.2418144-4-sashal@kernel.org> (raw)
In-Reply-To: <20211116190443.2418144-1-sashal@kernel.org>

From: Yang Li <yang.lee@linux.alibaba.com>

[ Upstream commit 458032fcfa91c8714859b1f01b9ac7dccea5d6cd ]

Although the callers of this function only care about whether the
return value is null or not, we should still give a rigorous
error code.

Smatch tool warning:
net/sunrpc/auth_gss/svcauth_gss.c:784 gss_write_verf() warn: returning
-1 instead of -ENOMEM is sloppy

No functional change, just more standardized.
