commitdfcc34c99fupstream. sync_request_write no longer submits writes to a Faulty device. This has the unfortunate side effect that bitmap bits can be incorrectly cleared if a recovery is interrupted (previously, end_sync_write would have prevented this). This means the next recovery may not copy everything it should, potentially corrupting data. Add a function for doing the proper md_bitmap_end_sync, called from end_sync_write and the Faulty case in sync_request_write. backport note to 4.14: s/md_bitmap_end_sync/bitmap_end_sync Cc: stable@vger.kernel.org 4.14+ Fixes:0c9d5b127f("md/raid1: avoid reusing a resync bio after error handling.")

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
