Fsync data recovery attempts to check and fix write pointer consistency of cursegs and all other zones. If the write pointers of cursegs are unaligned, cursegs are changed to new sections. If recovery fails, zone write pointers are still checked and fixed, but the latest checkpoint cannot be written back. Additionally, retry- mount skips recovery and rolls back to reuse the old cursegs whose zones are already finished. This can lead to unaligned write later. This patch addresses the issue by leaving writer pointers untouched if recovery fails. When retry-mount is performed, cursegs and other zones are checked and fixed after skipping recovery.

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 reStructuredText 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.
