Staging: lustre: Use put_unaligned_le64
This patch introduces the use of function put_unaligned_le64.
This is done using Coccinelle and semantic patch used is as follows:
@@ identifier tmp; expression ptr; expression y,e; type T; @@
- tmp = cpu_to_le64(y);
<+... when != tmp
- memcpy(ptr, (T)&tmp, ...);
+ put_unaligned_le64(y,ptr);
...+>
? tmp = e
@@ type T; identifier tmp; @@
- T tmp;
...when != tmp
