ext2fs: Add Direct I/O support to the ext2fs library This adds the basic support for Direct I/O to unix_io.c, and adds a new flag EXT_FLAG_DIRECT_IO which can be passed to ext2fs_open() or ext2fs_open2() to request Direct I/O support. Note that device mapper devices in Linux don't support Direct I/O, and in some circumstances using Direct I/O can actually make performance *worse*! Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
