From: Baokun Li Date: Tue, 8 Oct 2024 12:01:34 +0000 (+0800) Subject: ext4: show the default enabled prefetch_block_bitmaps option X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fdfa648ab9393de8c1be21cad17c17bdced3a68a;p=users%2Fjedix%2Flinux-maple.git ext4: show the default enabled prefetch_block_bitmaps option After commit 21175ca434c5 ("ext4: make prefetch_block_bitmaps default"), we enable 'prefetch_block_bitmaps' by default, but this is not shown in the '/proc/fs/ext4/sdx/options' procfs interface. This makes it impossible to distinguish whether the feature is enabled by default or not, so 'prefetch_block_bitmaps' is shown in the 'options' procfs interface when prefetch_block_bitmaps is enabled by default. This makes it easy to notice changes to the default mount options between versions through the '/proc/fs/ext4/sdx/options' procfs interface.
