mainlining shenanigans
kvmalloc() can allocate two types of objects: SLAB backed and vmalloc backed. How it behaves depends on requested object's size and memory pressure. Add a kvfree_rcu() interface that can free memory allocated via kvmalloc(). It is a simple alias to kfree_rcu() which can now handle either type of object. <snip> struct test_kvfree_rcu { struct rcu_head rcu; unsigned char array[100]; }; struct test_kvfree_rcu *p; p = kvmalloc(10 * PAGE_SIZE); if (p) kvfree_rcu(p, rcu); <snip> Signed-off-by: Uladzislau Rezki (Sony) <urezki@gmail.com> Co-developed-by: Joel Fernandes (Google) <joel@joelfernandes.org> Reviewed-by: Joel Fernandes (Google) <joel@joelfernandes.org> Signed-off-by: Joel Fernandes (Google) <joel@joelfernandes.org> Signed-off-by: Paul E.

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.
