Subject: [for-next][PATCH 01/14] tracing: Prefer kcalloc over kzalloc with multiply
Date: Sat, 29 Aug 2015 11:02:16 -0400 [thread overview]
Message-ID: <20150829150238.097953414@goodmis.org> (raw)
In-Reply-To: 20150829150215.458315917@goodmis.org
[-- Attachment #1: 0001-tracing-Prefer-kcalloc-over-kzalloc-with-multiply.patch --]
[-- Type: text/plain, Size: 951 bytes --]
From: Gil Fruchter <gilf@ezchip.com>
Use kcalloc for allocating an array instead of kzalloc with multiply,
as that is what kcalloc is used for.
Found with checkpatch.
