Subject: [PATCH v3 03/10] ext4: warn if delalloc counters are not zero on inactive
Date: Wed, 8 May 2024 14:12:13 +0800 [thread overview]
Message-ID: <20240508061220.967970-4-yi.zhang@huaweicloud.com> (raw)
In-Reply-To: <20240508061220.967970-1-yi.zhang@huaweicloud.com>
From: Zhang Yi <yi.zhang@huawei.com>
The per-inode i_reserved_data_blocks count the reserved delalloc blocks
in a regular file, it should be zero when destroying the file. The
per-fs s_dirtyclusters_counter count all reserved delalloc blocks in a
filesystem, it also should be zero when umounting the filesystem. Now we
have only an error message if the i_reserved_data_blocks is not zero,
which is unable to be simply captured, so add WARN_ON_ONCE to make it
more visable.
