Method forEachMappingSlice

pkg/sentry/pgalloc/pgalloc.go:1466–1471

forEachMappingSlice invokes fn on a sequence of byte slices that collectively map all bytes in fr.

(fr memmap.FileRange, fn func([]byte))

// forEachMappingSlice invokes fn on a sequence of byte slices that
// collectively map all bytes in fr.
func (f *MemoryFile) forEachMappingSlice(fr memmap.FileRange, fn func([]byte)) {
	f.forEachChunk(fr, func(chunk *chunkInfo, chunkFR memmap.FileRange) bool {
		fn(chunk.sliceAt(chunkFR))
		return true
	})
}

// MarkEvictable allows f to request memory deallocation by calling
// user.Evict(er) in the future.
