When an app in a FUSE mount calls getdents(2), go-fuse receives READDIR[PLUS] and calls the filesystem's OpenDir function that returns []DirEntry. The data returned from getdents(2) contains an inode number for each directory entry, "d_ino". Until now, struct DirEntry had no corresponding field and the value passed to the kernel was always FUSE_UNKNOWN_INO = 0xffffffff This broke apps that actually look at the d_ino field, like "find -inum". This commit adds the "Ino" filed to struct DirEntry. If the field is not set by the filesystem, it is set to FUSE_UNKNOWN_INO, as before. Otherwise it is left alone and passed to the kernel. loopbackFileSystem's OpenDir function is extended to set the inode number. A test verifies that the returned inode number is sane.
