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

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.
