Subject: [PATCH] net: cavium: liquidio: Use vzalloc instead of vmalloc
Date: Sat, 18 Jun 2016 12:23:20 +0530 [thread overview]
Message-ID: <20160618065320.GA1906@amitoj-Inspiron-3542> (raw)
vzalloc combines vmalloc and memset 0.
The Coccinelle semantic patch used to make this change is as follows:
@@
type T;
T *d;
expression e;
statement S;
@@
d =
- vmalloc
+ vzalloc
(...);
if (!d) S
- memset(d, 0, sizeof(T));
