In jbd2_journal_commit_transaction(), if we are in abort mode, we may flush the buffer without setting descriptor block checksum by goto start_journal_io. Then fs is mounted, jbd2_descriptor_block_csum_verify() failed. [ 271.379811] EXT4-fs (vdd): shut down requested (2) [ 271.381827] Aborting journal on device vdd-8. [ 271.597136] JBD2: Invalid checksum recovering block 22199 in log [ 271.598023] JBD2: recovery failed [ 271.598484] EXT4-fs (vdd): error loading journal Fix this problem by keep setting descriptor block checksum if the descriptor buffer is not NULL. This checksum problem can be reproduced by xfstests generic/388. Signed-off-by: luojiajun <luojiajun3@huawei.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Jan Kara <jack@suse.cz> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
