Subject: [PATCH v6 4/6] fsmonitor: avoid socket location check if using hook

From: "Eric DeCosta via GitGitGadget" <[email-masked]>
Date: Tue, 13 Sep 2022 20:27:36 +0000

From: Eric DeCosta <[email-masked]>

If monitoring is done via fsmonitor hook rather than IPC there is no
need to check if the location of the Unix Domain socket (UDS) file is
on a remote filesystem.
