Keep the mount superblock counters up to date for !lazysbcount filesystems so that when we log the superblock they do not need updating in any way because they are already correct. It's found by what Zorro reported: 1. mkfs.xfs -f -l lazy-count=0 -m crc=0 $dev 2. mount $dev $mnt 3. fsstress -d $mnt -p 100 -n 1000 (maybe need more or less io load) 4. umount $mnt 5. xfs_repair -n $dev and I've seen no problem with this patch.

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.
