Martin KaFai Lau says: ==================== From: Martin KaFai Lau <martin.lau@kernel.org> This set is a continuation of the effort in using bpf_mem_cache_alloc/free in bpf_local_storage [1] Major change is only using bpf_mem_alloc for task and cgrp storage while sk and inode stay with kzalloc/kfree. The details is in patch 2. [1]: https://lore.kernel.org/bpf/20230308065936.1550103-1-martin.lau@linux.dev/ v3: - Only use bpf_mem_alloc for task and cgrp storage. - sk and inode storage stay with kzalloc/kfree. - Check NULL and add comments in bpf_mem_cache_raw_free() in patch 1. - Added test and benchmark for task storage. v2: - Added bpf_mem_cache_alloc_flags() and bpf_mem_cache_raw_free() to hide the internal data structure of the bpf allocator. - Fixed a typo bug in bpf_selem_free() - Simplified the test_local_storage test by directly using err returned from libbpf ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
