SLAB_RECLAIM_ACCOUNT caches allocate their slab pages with __GFP_RECLAIMABLE and can help against fragmentation by grouping pages by mobility, but on tiny systems mobility grouping is likely disabled anyway and ignoring SLAB_RECLAIM_ACCOUNT might instead lead to merging of caches that are made incompatible just by the flag. Thus with CONFIG_SLUB_TINY, make SLAB_RECLAIM_ACCOUNT ineffective.

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.
