Subject: [PATCHv9-rebased2 24/37] filemap: prepare find and delete operations for huge pages
Date: Wed, 15 Jun 2016 23:06:29 +0300 [thread overview]
Message-ID: <1466021202-61880-25-git-send-email-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <1466021202-61880-1-git-send-email-kirill.shutemov@linux.intel.com>
For now, we would have HPAGE_PMD_NR entries in radix tree for every huge
page. That's suboptimal and it will be changed to use Matthew's
multi-order entries later.
'add' operation is not changed, because we don't need it to implement
hugetmpfs: shmem uses its own implementation.
