  • libcsupport/Makefile.am: Add mount-mgr.c.
  • libcsupport/src/mount-mgr.c: New.
  • include/rtems/fs.h: Added rtems_filesystem_location_mount.
  • libcsupport/include/rtems/libio.h, libcsupport/src/mount.c: New mount interface. It is similar to Linux.
  • libcsupport/include/rtems/libio_.h: Remove the init_fs_mount_table call.
  • libcsupport/src/base_fs.c: Remove init_fs_mount_table_call. Use the new mount call. Remove setting the root node in the global pathloc. Mount does this now.
  • libcsupport/src/privateenv.c: Remove the hack to set the root mount table entry in the environment.
  • libcsupport/src/unmount.cL Free the target string.
  • libblock/src/bdpart-mount.c: New mount API.
  • libfs/src/devfs/devfs.h, libfs/src/devfs/devfs_init.c, libfs/src/dosfs/dosfs.h, libfs/src/dosfs/msdos.h, libfs/src/dosfs/msdos_init.c, libfs/src/imfs/imfs.h, libfs/src/imfs/imfs_eval.c, libfs/src/imfs/imfs_init.c, libfs/src/imfs/miniimfs_init.c, libfs/src/nfsclient/src/librtemsNfs.h, libfs/src/rfs/rtems-rfs-rtems.c, libfs/src/rfs/rtems-rfs.h, libnetworking/lib/ftpfs.c, libnetworking/rtems/ftpfs.h, libnetworking/rtems/tftp.h: New mount_h API.
  • libfs/src/devfs/devfs_eval.c: Local include of extern ops.
  • libfs/src/nfsclient/src/nfs.c: New mount API. Removed the mount me call and fixed the initialisation to happen when mounting.
  • libmisc/Makefile.am, libmisc/shell/shellconfig.h: Remove mount filesystem files.
  • libmisc/fsmount/fsmount.c, libmisc/fsmount/fsmount.h: Updated to the new mount table values.
  • libmisc/shell/main_mount_ftp.c, libmisc/shell/main_mount_msdos.c, libmisc/shell/main_mount_rfs.c, libmisc/shell/main_mount_tftp.c: Removed.
  • libmisc/shell/main_mount.c: Use the new mount API. Also access the file system table for the file system types.
  • libnetworking/lib/tftpDriver.c: Updated to the new mount API. Fixed to allow mounting from any mount point. Also can now have more than file system mounted.
  • sapi/include/confdefs.h: Add file system configuration support.
  • Property mode set to 100644
