From bd25bf9dcd3c3d57a22a04bd73845911d33e3ac1 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Wed, 18 Dec 2024 12:48:39 +0000 Subject: [PATCH] btrfs: ioctl: remove unnecessary call to btrfs_mark_buffer_dirty() The call to btrfs_mark_buffer_dirty() at btrfs_ioctl_default_subvol() is not necessary as we have a path setup for writing with btrfs_search_slot() having a 'cow' argument set to 1. This just makes the code more verbose, confusing and add a little extra overhead and well as increase the module's text size, so remove it.
