+Subject: nfsd: apply umask on fs without ACL support
+
+From: J. Bruce Fields <bfields@redhat.com>
+
+commit 22cf8419f1319ff87ec759d0ebdff4cbafaee832 upstream.
+
+The server is failing to apply the umask when creating new objects on
+filesystems without ACL support.
+
+To reproduce this, you need to use NFSv4.2 and a client and server
+recent enough to support umask, and you need to export a filesystem that
+lacks ACL support (for example, ext4 with the "noacl" mount option).
+
+Filesystems with ACL support are expected to take care of the umask
+themselves (usually by calling posix_acl_create).
+
+For filesystems without ACL support, this is up to the caller of
+vfs_create(), vfs_mknod(), or vfs_mkdir().

+Subject: Revert "ALSA: usb-audio: Improve frames size computation"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 99703c921864a318e3e8aae74fde071b1ff35bea which is
+commit f0bd62b64016508938df9babe47f65c2c727d25c upstream.
+
+It causes a number of reported issues and a fix for it has not hit
+Linus's tree yet.  Revert this to resolve those problems.
