Store the RAID stride value when a filesystem is created with a requested
RAID stride, and then use it automatically in resize2fs.

Change all of the e2fsprogs programs to use the newer add_error_table()
and remove_error_table() interfaces instead of the much older
initialize_*_error_table() function.

Resize2fs will now automatically determine the RAID stride parameter that
had been used to create the filesystem, and use that for newly created
block groups. The RAID stride parameter may also be manually specified
on the command line using the new -S option to resize2fs.

Change the format string(%d, %ld) for a block number and inode number
to %u or %lu.

If the filesystem is mounted, open it in read-only mode since the userspace
program should not try to modify it directly. If the filesystem is not mounted,
open it in exclusive mode to avoid potential problems (such as someone
trying to mount the filesystem while it is being resized).

the & character, although at the moment the only option implemented is
the offset option in the unix_io layer.

display explicitly the blocksize used by the filesystem,
to avoid confusion. (Addresses Debian bug: #189814)
than the requested size, then we will attempt to
transparently extend the filesize in a sparse fashion by
writing a block at the end of the requested part of the
filesystem.
main.c (main), resize2fs.c (resize_fs), resize2fs.h: Change the
function prototype of resize_fs() so that it can modify
the new_size parameter with the actual new size of the
filesystem after the resize operation. (This can
sometimes be less than the requested new size if there
isn't enough space to create the necessary block group
metadata for that last bit of disk space.) Resize2fs now
prints the actual new size of the filesystem when it finishes.
ext2fs.h: Remove definition of ext2fs_sb. Note: this may break source
(but not binary) compatibility of some users of the ext2 library.
They should just simply do a global search and replace of struct
ext2fs_sb with struct ext2_super_block, and use their own private copy
of ext2_fs.h if they aren't already.
closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c: Replace
use of ext2fs_sb with ext2_super_block.
ChangeLog, main.c:
main.c (main): Replace use of struct ext2fs_sb with struct ext2_super_block.
Update copyright of files in preparation for release of resize2fs.
Also removed the (obsolete) beta-test check that had been in the code,
as well as the old spec files used to package the separate
distribution of resize2fs.
Makefile.in: No longer build resize2fs.static, since there's no real
point in it any more.

main.c (main): Check to make sure we can really resize this
filesystem. If there are compatible feature sets that we don't
support, we need to abort.
resize2fs.c: Change to use the new prototype required by
block_iterate2 (which uses blkcnt_t for the blockcount).
version.h, RELEASE-NOTES:
Interim commit of changes to date.
Makefile.in: Add rule to build a static version of resize2fs. Update
dependency rules.
main.c: #include ../version.h, instead of using a hard-coded version
string.
main.c (check_mount, main): Resize2fs now checks the size of the
partition, and uses this as a default new_size of the partition if one
is not specified. Resize2fs will not let you resize a mounted
partition.
resize2fs.c: Change how the progress function for the INODE_SCAN pass
is performed, so that the maximum size is never zero.
resize2fs.8.in: Updated man page.
Major reoganization of how resizing works. Functions in
ext2_block_move.c, and ext2_inode_move.c moved into resize2fs.c.
Multiple passes in those two files also combined into a single inode
scanning pass. Made the inode table moving function better handling
the case where it needs to abort mid-operation. When moving blocks
around, made the block allocation function preferentially avoid the
old group descriptor blocks, to make resize2fs more robust.
resize2fs.c, ext2_block_move.c ext2_inode_move.c: Only include printf
statements if RESIZE2FS_DEBUG is defined.
main.c: Don't read in the bitmaps since resize2fs.c does that.
e2label.c, mke2fs.c:
Adjust header files.
Allow people to set the version.h to something like 1.10-PLUS.
.del-inodemap.c~24510e64, main.c, resize2fs.c, resize2fs.h:
More interim work. All is functioning except progress meter.
bmove.c (ext2fs_move_blocks): New function which takes a bitmap of
blocks which need to be moved, and moves those blocks to another
location in the filesystem.
rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a bitmap,
make sure all of the new parts of the bitmap are zero.
bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap wasn't
being returned to the caller.
alloc_tables.c (ext2fs_allocate_group_table): Add new function
ext2fs_allocate_group_table() which sets the group tables for a
particular block group. The relevant code was factored out of
ext2fs_allocate_tables().
dblist.c (make_dblist): Adjust the initial size of the directory block
list to be a bit more realize (ten plus twice the number of
directories in the filesystem).
Check in interim work.
configure.in (rmakefile): Added (optional) private directory for resize2fs.
Makefile.in: Change recursive descent rules to check to see if a
directory exists before trying to make it.
Many files:
Initial checkin of work done to date.
