  • libblock/src/bdbuf.c: Update comments.
  • libblock/src/bdpart.c, libblock/src/ide_part_table.c: Get the device from the rdev field of the stat buf.
  • libcsupport/include/rtems/libio.h: Add a path length to evalpath handler. Add parent locations to rmmod and unlink handlers.
  • libcsupport/include/rtems/libio_.h: Add a path length to rtems_filesystem_evaluate_path. Add rtems_filesystem_evaluate_relative_path, rtems_filesystem_dirname, and rtems_filesystem_prefix_separators. Remove rtems_filesystem_evaluate_parent.

  • libcsupport/src/eval.c: Add rtems_filesystem_prefix_separators, rtems_filesystem_dirname, rtems_filesystem_evaluate_relative_path. Add the length parameter to the eval call.
  • libcsupport/src/rmdir.c: Find the parent pathloc then the node pathloc from that node. Remove the call to find the parent given the node pathloc.
  • libcsupport/src/stat.c: Add the length parameter to the eval call. Set the device into the rdev field.
  • libcsupport/src/unlink.c: Find the parent pathloc then the node pathloc from that node. Remove the call to find the parent given the node pathloc.
  • libfs/src/dosfs/fat.c, libfs/src/dosfs/msdos_format.c: Get the disk device number from the stat rdev field.
  • libfs/src/dosfs/msdos.h: Add the length parameter to the eval call. Add the parent pathloc to the rmnod handler.
  • libfs/src/dosfs/msdos_dir.c: Add the parent pathloc to the rmnod handler.
