Currently the following members of scrub_stripe are only utilized for error reporting: - init_error_bitmap - init_nr_io_errors - init_nr_csum_errors - init_nr_meta_errors - init_nr_meta_gen_errors There is no need to put all those members into scrub_stripe, which take 24 bytes for each stripe, and we have 128 stripes for each device. Instead introduce a structure, scrub_error_records, and move all above members into that structure. And allocate such structure from stack inside scrub_stripe_read_repair_worker(). Since that function is called from a workqueue context, we have more than enough stack space for just 24 bytes.

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.
