From: Anna Schumaker <anna@kernel.org>

From: Anna Schumaker <redacted> This is similar to xdr_encode_word(), but instead lets us encode a 64-bit wide value into the xdr_buf at the given offset. Signed-off-by: Anna Schumaker <redacted> --- include/linux/sunrpc/xdr.h | 1 + net/sunrpc/xdr.c | 8 ++++++++ 2 files changed, 9 insertions(+)
