More stack usage improvements: instead of creating a new alloc_request (currently on the stack), save/restore just the fields we need to reuse. This is a bit tricky, because we're doing a normal alloc_foreground.c allocation, which calls into ec.c to get a stripe, which then does more normal allocations - some of the fields get reused, and used differently. So we have to save and restore them - but the stack usage improvements will be well worth it. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
