      Description

      The lfs ladvise functionality was added in LU-4931 to allow the client to prefetch data into OSS cache via willread and to drop it from cache via dontneed. ZFS has functionality to implement willread, but is missing the dontneed functionality to drop pages from the OSS cache.
