Test refcounted local kptr functionality added in previous patches in the series. Usecases which pass verification: * Add refcounted local kptr to both tree and list. Then, read and - possibly, depending on test variant - delete from tree, then list. * Also test doing read-and-maybe-delete in opposite order * Stash a refcounted local kptr in a map_value, then add it to a rbtree. Read from both, possibly deleting after tree read. * Add refcounted local kptr to both tree and list. Then, try reading and deleting twice from one of the collections. * bpf_refcount_acquire of just-added non-owning ref should work, as should bpf_refcount_acquire of owning ref just out of bpf_obj_new Usecases which fail verification: * The simple successful bpf_refcount_acquire cases from above should both fail to verify if the newly-acquired owning ref is not dropped Signed-off-by: Dave Marchevsky <davemarchevsky@fb.com> Link: https://lore.kernel.org/r/20230415201811.343116-10-davemarchevsky@fb.com 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.
