fs/ceph/xattr.c: Use kmemdup
Convert a sequence of kmalloc and memcpy to use kmemdup.
The semantic patch that performs this transformation is:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression a,flag,len;
expression arg,e1,e2;
statement S;
@@
a =
- \(kmalloc\|kzalloc\)(len,flag)
+ kmemdup(arg,len,flag)
<... when != a
if (a == NULL || ...) S
...>
- memcpy(a,arg,len+1);
// </smpl>
