Required Methods

fn remove_range(&self, mem_offset: usize, count: usize) -> Result<(), Error>

Remove the specified range from the mapping.

fn async_prefetch(&self, mem_offset: usize, count: usize) -> Result<(), Error>

Tell the kernel to readahead the range.

fn drop_page_cache(&self, mem_offset: usize, count: usize) -> Result<(), Error>

Tell the kernel to drop the page cache.

fn lock_on_fault(&self, mem_offset: usize, count: usize) -> Result<(), Error>

Lock the resident pages in the range not to be swapped out.

fn unlock(&self, mem_offset: usize, count: usize) -> Result<(), Error>

Unlock the range of pages.

fn lock_all(&self) -> Result<(), Error>

Disable host swap for this mapping.
