When committing era metadata to disk, it doesn't always save the latest spacemap metadata root in superblock. Due to this, metadata is getting corrupted sometimes when reopening the device. The correct order of update should be, pre-commit (shadows spacemap root), save the spacemap root (newly shadowed block) to in-core superblock and then the final commit.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
