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 Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
