Merge tag 'ecryptfs-3.9-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs
Pull ecryptfs fixes from Tyler Hicks: "Minor code cleanups and new Kconfig option to disable /dev/ecryptfs The code cleanups fix up W=1 compiler warnings and some unnecessary checks. The new Kconfig option, defaulting to N, allows the rarely used eCryptfs kernel to userspace communication channel to be compiled out. This may be the first step in it being eventually removed." Hmm. I'm not sure whether these should be called "fixes", and it probably should have gone in the merge window. But I'll let it slide. * tag 'ecryptfs-3.9-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: eCryptfs: allow userspace messaging to be disabled eCryptfs: Fix redundant error check on ecryptfs_find_daemon_by_euid() ecryptfs: ecryptfs_msg_ctx_alloc_to_free(): remove kfree() redundant null check eCryptfs: decrypt_pki_encrypted_session_key(): remove kfree() redundant null check eCryptfs: remove unneeded checks in virt_to_scatterlist() eCryptfs: Fix -Wmissing-prototypes warnings eCryptfs: Fix -Wunused-but-set-variable warnings eCryptfs: initialize payload_len in keystore.c
