+Subject: [PATCH] eCryptfs: Fix directory open regression in linux-stable
+Newsgroups: gmane.comp.file-systems.ecryptfs.general, gmane.linux.kernel.stable
+Date: 2016-06-29 03:39:41 GMT (14 hours and 12 minutes ago)
+
+Cherry-picking mainline commit 2f36db71009304b3f0b95afacd8eba1f9f046b87
+introduces a regression in eCryptfs when mainline commit
+6a480a7842545ec520a91730209ec0bae41694c1 (4.6+) is not present. The
+regression causes all attempts at opening directory files to fail with
+EMEDIUMTYPE when the lower filesystem's file_operations for directory
+files do not implement mmap.
+
+This is a simple fix that allows the check for the lower file's mmap
+implementation to be ignored if the lower file is a directory.
