Subject: [PATCH v2] f2fs: avoid attaching SB_ACTIVE flag during mount
Date: Wed, 1 Sep 2021 16:06:21 +0800 [thread overview]
Message-ID: <20210901080621.110319-1-chao@kernel.org> (raw)
Quoted from [1]
"I do remember that I've added this code back then because otherwise
orphan cleanup was losing updates to quota files. But you're right
that now I don't see how that could be happening and it would be nice
if we could get rid of this hack"
[1] https://lore.kernel.org/linux-ext4/99cce8ca-e4a0-7301-840f-2ace67c551f3@huawei.com/T/#m04990cfbc4f44592421736b504afcc346b2a7c00
Related fix in ext4 by
commit 72ffb49a7b62 ("ext4: do not set SB_ACTIVE in ext4_orphan_cleanup()").
f2fs has the same hack implementation in
- f2fs_recover_orphan_inodes()
- f2fs_recover_fsync_data()
Let's get rid of this hack as well in f2fs.
