From df9d70c18616760c6504b97fec66b6379c172dbb Mon Sep 17 00:00:00 2001 From: Bharath SM bharathsm@microsoft.com Date: Fri, 7 Jul 2023 15:29:01 +0000 Subject: [PATCH] cifs: if deferred close is disabled then close files immediately
If defer close timeout value is set to 0, then there is no need to include files in the deferred close list and utilize the delayed worker for closing. Instead, we can close them immediately.
