If the resize operation fails in the middle of the operation, mark the
filesystem as needing to be checked, and tell the user that they
should run e2fsck -fy on the device.

The resize2fs program was freeing the mountpoint information too
early, so garbage was getting printed instead of the correct
information in an error message.

Without a force flag, don't allow resize2fs to even start resizing
below what it thinks the minimum safe value is.
This may stop resizes which could otherwise proceed with a bit
of space still left, but seems like a reasonably safe thing to do.

Resize2fs will attempt to truncate an image file of a filesystem down
to size for the convenience of the system administrator. If the
truncate operation fails, print a warning message. This also avoids a
gcc warning message.

If we don't check for new_size == 0, bogus values send resize2fs into
a tailspin:
resize2fs 1.41.0 (10-Jul-2008)
Illegal block number passed to ext2fs_test_block_bitmap #1 for block bitmap for
/tmp/tmp.lntZtMFvz8/fake-disk
...the same message repeated zillion times...
Probably should see where that loop is, but at any rate we should
error-check parse_num_blocks.
Thanks to Petr Muller for reporting this.

do so if the environment variables TEST_IO_FLAGS and TEST_IO_DEBUG are

Apparently Mac OS 10.5 defines fstat64(), but not ftruncate64(),
causing resize2fs to fail to build. So check explicitly for
ftruncate64(), and fall back to ftruncate() if necessary.
Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
If we can't use ftruncate64(), and have to use ftruncate() instead,
make sure that we don't accidentally truncate the size when we chop it
down to an off_t before calling ftruncate(), lest we severely damage a
filesystem image file.

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.

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).

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.

main.c (main): Replace use of struct ext2fs_sb with struct ext2_super_block.
