commit1d1f25bfdaupstream. Don't update recovery_cp when curr_resync is MD_RESYNC_ACTIVE, otherwise md may skip the resync of the first 3 sectors if the resync procedure is interrupted before the first calling of ->sync_request() as shown below: md_do_sync thread control thread // setup resync mddev->recovery_cp = 0 j = 0 mddev->curr_resync = MD_RESYNC_ACTIVE // e.g., set array as idle set_bit(MD_RECOVERY_INTR, &&mddev_recovery) // resync loop // check INTR before calling sync_request !test_bit(MD_RECOVERY_INTR, &mddev->recovery // resync interrupted // update recovery_cp from 0 to 3 // the resync of three 3 sectors will be skipped mddev->recovery_cp = 3 Fixes:eac58d08d4("md: Use enum for overloaded magic numbers used by mddev->curr_resync") Cc: stable@vger.kernel.org # 6.0+ Signed-off-by: Hou Tao <houtao1@huawei.com> Reviewed-by: Logan Gunthorpe <logang@deltatee.com> Signed-off-by: Song Liu <song@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
