exofs: dir_inode and directory operations
implementation of directory and inode operations. * A directory is treated as a file, and essentially contains a list of <file name, inode #> pairs for files that are found in that directory. The object IDs correspond to the files' inode numbers and are allocated using a 64bit incrementing global counter. * Each file's control block (AKA on-disk inode) is stored in its object's attributes. This applies to both regular files and other types (directories, device files, symlinks, etc.). Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
