From 740b8bf87322701b4607b77346477cbc764f5c56 Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Sat, 17 Dec 2022 17:05:47 +0000 Subject: [PATCH] fs/9p: Remove unnecessary superblock flags These flags just add unnecessary extra operations. When 9p is run without cache, it inherently implements these options so we don't need them in the superblock (which ends up sending extraneous fsyncs, etc.). User can still request these options on mount, but we don't need to set them as default.
