Function k_mem_unmap_phys_guard

pub unsafe extern "C" fn k_mem_unmap_phys_guard(
    addr: *mut c_void,
    size: usize,
    is_anon: bool,
)

Un-map memory mapped via k_mem_map_phys_guard().

This removes the memory mappings for the provided page-aligned region, and the two guard pages surrounding the region.

This function alters the active page tables in the area reserved for the kernel.

@see k_mem_unmap() for additional information if called via that.

@note Calling this function on a region which was not mapped via k_mem_map_phys_guard() to begin with is undefined behavior.

@param addr Page-aligned memory region base virtual address @param size Page-aligned memory region size @param is_anon True if the mapped memory is from anonymous memory.
