- Makefile.am, preinstall.am: Added statvfs.h.
- libcsupport/Makefile.am: Add statvfs.c.
- libcsupport/include/sys/statvfs.h, libcsupport/src/statvfs.c:
New.
- libcsupport/include/rtems/libio.h: Add a file system handler for
the statvfs call.
- libfs/src/devfs/devfs_init.c, libfs/src/dosfs/msdos_init.c,
libfs/src/imfs/imfs_init.c, libfs/src/nfsclient/src/nfs.c: Set the
statvfs handler to NULL.
- include/rtems/fs.h: Add a second node access field for the RFS
file system to hold a directory offset while the existing field
holds the inode number. This save a rescan of the directory when
working with directories.
- libblock/include/rtems/bdbuf.h: Added references and user fields
to the buffer descriptor.
- libblock/src/bdbuf.c: Added dynamic buffer support for different
block sizes. Fixed a number of bugs.
- libblock/src/blkdev.c: Release the disk device on an error.
- libblock/src/diskdevs.c: Set the block size to the media block
size during initialisation of the disk device.
- libblock/src/flashdisk.c, libblock/src/nvdisk.c,
libblock/src/ramdisk.c: Updated the drivers to handle variable
block sizes.
- libfs/src/dosfs/fat.c, libfs/src/dosfs/fat.h: Release any
buffers when an error occurs. The FAT buffer layer hangs onto a
single buffer while mounted. This should be fixed.
- sapi/inline/rtems/chain.inl: Added rtems_chain_set_off_chain,
rtems_chain_is_node_off_chain, and rtems_chain_previous.
- score/inline/rtems/score/chain.inl: Added _Chain_Set_off_chain,
and _Chain_Is_node_off_chain.
- libmisc/shell/main_ln.c, libmisc/shell/main_mknod.c,
libmisc/shell/mknod-pack_dev.c, libmisc/shell/mknod-pack_dev.h:
New shell commands.
- libmisc/Makefile.am, libmisc/shell/shellconfig.h: Added ln and
mknod commands.
- libmisc/shell/hexdump-display.c: Fixed the reopen bug which
showed up as a free with a bad pointer.
- libmisc/shell/main_mount.c: List the user adding file system
when listing the available file systems to mount.
- libmisc/shell/utils-cp.c: Remove the fixed static copy buffer
and use a large dynamic buffer.
- score/inline/rtems/score/address.inl, score/src/coremsgsubmit.c,
score/src/objectallocate.c, score/src/objectfree.c: Remove
warnings.
