I'd like to continue > tests for a couple more days before I send you the pull request. v2 fixes the following issues: - Fix up the cookie usage in uncached_readdir() - Changelog fixups for the second patch - .releasepage should use kmap_atomic() so that it can be called from all direct reclaim contexts. - Ensure that .releasepage also clears Pg_uptodate - Set/clear the Pg_private flag to ensure .releasepage gets called when appropriate. - Add a .invalidatepage to ensure truncate_inode_pages() works correctly - Ensure that the anonymous page that is generated by uncached_readdir() doesn't leak memory. v3: - add the freepage() address space operation. - Dump the page locking - rewrite patch 'Fix a memory leak in nfs_readdir' to work with the new ->freepage() callback.
