eCryptfs: read_write.c routines
Add a set of functions through which all I/O to lower files is consolidated. This patch adds a new inode_info reference to a persistent lower file for each eCryptfs inode; another patch later in this series will set that up. This persistent lower file is what the read_write.c functions use to call vfs_read() and vfs_write() on the lower filesystem, so even when reads and writes come in through aops->readpage and aops->writepage, we can satisfy them without resorting to direct access to the lower inode's address space. Several function declarations are going to be changing with this patchset. For now, in order to keep from breaking the build, I am putting dummy parameters in for those functions.
