From 8c38b705b4f4ca4e7f9cc116141bc38391917c30 Mon Sep 17 00:00:00 2001 From: Rik van Riel Date: Mon, 14 Sep 2020 13:07:19 -0400 Subject: silence nfscache allocation warnings with kvzalloc silence nfscache allocation warnings with kvzalloc Currently nfsd_reply_cache_init attempts hash table allocation through kmalloc, and manually falls back to vzalloc if that fails. This makes the code a little larger than needed, and creates a significant amount of serial console spam if you have enough systems. Switching to kvzalloc gets rid of the allocation warnings, and makes the code a little cleaner too as a side effect. Freeing of nn->drc_hashtbl is already done using kvfree currently.
