  • 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/base_fs.c, libcsupport/src/chdir.c, libcsupport/src/chmod.c, libcsupport/src/chown.c, libcsupport/src/chroot.c, libcsupport/src/fchdir.c, libcsupport/src/link.c, libcsupport/src/mount.c, libcsupport/src/open.c, libcsupport/src/privateenv.c, libcsupport/src/readlink.c, libcsupport/src/unmount.c, libcsupport/src/utime.c, libcsupport/src/unmount.c, libcsupport/src/utime.c, libfs/src/devfs/devfs.h, libfs/src/devfs/devfs_eval.c, libfs/src/devfs/devstat.c, libfs/src/dosfs/msdos_create.c, libfs/src/dosfs/msdos_misc.c, libfs/src/imfs/imfs.h, libfs/src/imfs/imfs_eval.c, libfs/src/imfs/imfs_load_tar.c, libfs/src/imfs/ioman.c, libfs/src/pipe/pipe.c, libmisc/fsmount/fsmount.c, libnetworking/lib/ftpfs.c: Add the length parameter to the eval call.
  • 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.
  • libfs/src/dosfs/msdos_eval.c: Add the length parameter to the eval and token call.
  • libfs/src/imfs/imfs_directory.c: Add the parent pathloc to the rmnod handler.
  • libfs/src/imfs/imfs_fchmod.c: Do not test the mode flags for only the allowed flags. Add the missing flags spec'ed in the POSIX standard.
