Currently we store the following members in scrub_sector: - logical - physical - physical_for_dev_replace - dev - mirror_num However the current scrub code has ensured that scrub_blocks never cross stripe boundary. This is caused by the entry functions (scrub_simple_mirror, scrub_simple_stripe), thus every scrub_block will not cross stripe boundary. Thus this makes it possible to move those members into scrub_block other than putting them into scrub_sector. This should save quite some memory, as a scrub_block can be as large as 64 sectors, even for metadata it's 16 sectors byte default.

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.
