Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull more vfs updates from Al Viro: "A couple of fixes + getting rid of __blkdev_put() return value" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: proc: Use PDE attribute setting accessor functions make blkdev_put() return void block_device_operations->release() should return void mtd_blktrans_ops->release() should return void hfs: SMP race on directory close()
