[SRU J/K/HWE-5.17/OEM-5.14 7/8] NFSD: Remove "inline" directives on op_rsize_bop helpers
Thadeu Lima de Souza Cascardo

Fri Nov 11 13:48:29 UTC 2022
From: Chuck Lever <chuck.lever at oracle.com>
These helpers are always invoked indirectly, so the compiler can't
inline these anyway. While we're updating the synopses of these
helpers, defensively convert their parameters to const pointers.

(cherry picked from commit 6604148cf961b57fc735e4204f8996536da9253c)
CVE-2022-43945
