Chuck LeverandGreg Kroah-Hartman 6943f1073a SUNRPC: Optimize xdr_reserve_space() ...

[ Upstream commit 62ed448cc5 ]

Transitioning between encode buffers is quite infrequent. It happens
about 1 time in 400 calls to xdr_reserve_space(), measured on NFSD
with a typical build/test workload.

Force the compiler to remove that code from xdr_reserve_space(),
which is a hot path on both the server and the client. This change
reduces the size of xdr_reserve_space() from 10 cache lines to 2
when compiled with -Os.
