  "message": "mm: clarify the radix_tree exceptional cases\n\nMake the radix_tree exceptional cases, mostly in filemap.c, clearer.\n\nIt\u0027s hard to devise a suitable snappy name that illuminates the use by\nshmem/tmpfs for swap, while keeping filemap/pagecache/radix_tree\ngenerality.  And akpm points out that /* radix_tree_deref_retry(page) */\ncomments look like calls that have been commented out for unknown\nreason.\n\nSkirt the naming difficulty by rearranging these blocks to handle the\ntransient radix_tree_deref_retry(page) case first; then just explain the\nremaining shmem/tmpfs swap case in a comment.\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
