__d_internal. * fhandler_disk_file.cc (struct __DIR_cache): Remove useless "typedef". (d_dirname): Remove useless "struct". (d_cachepos): Ditto. (d_cache): Ditto. (class __DIR_mounts): New class, implementing mount point tracking for readdir. (d_mounts): New macro for easy access to __DIR_mounts structure. (fhandler_disk_file::opendir): Allocate __DIR_mounts structure and let __d_internal element of dir point to it. (fhandler_disk_file::readdir_helper): Add mount points in the current directory, which don't have a real directory backing them. Don't generate an inode number for /dev. Add comment, why. (fhandler_disk_file::readdir): Move filling fname to an earlier point. Check if current entry is a mount point and evaluate correct inode number for it. (fhandler_disk_file::readdir_9x): Ditto. (fhandler_disk_file::rewinddir): Set all mount points in this directory to "not found" so that they are listed again after calling rewinddir(). (fhandler_disk_file::closedir): Deallocate __DIR_mounts structure. * path.cc (mount_info::get_mounts_here): New method to evaluate a list of mount points in a given parent directory. * shared_info.h (class mount_info): Declare get_mounts_here.
