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> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Sage Weil <sage@newdream.net>
