Subject: [RFC,PATCH] 64-bit support for e2fsprogs

This is my incomplete current 64-bit e2fsprogs patchset for review and
comment (not inclusion).  Only lib/ext2fs/, misc/mke2fs.c, and e2fsck/
have been converted to 64-bit interfaces so far (and those not
completely).  As of this patch set, mke2fs can create a file system
with > 2^32 blocks.  However, it can't be mounted due to invalid
checksums on the group descriptors. :)

This series is based on the 64-bit patches by Ted T'so and Jose
R. Santos.  It includes:

* Two housekeeping patches (workaround make check error, fix warnings)
* 64-bit bitops and bitmaps
* Conversion of all of e2fsprogs to 64-bit bitmap interfaces
* Partial conversion of e2fprogs to other 64-bit interfaces
* Miscellaneous 64-bit bug fixes

Use the following mke2fs command to produce a file system with more
than 2^32 blocks:

$ mke2fs -t ext4 -O 64bit -b 4096 -N 200000 <device>

These patches apply against the pu branch, commit ID:

6db77ec039ff241dab0f1e267fabcfa814fbaf4c

All commits pass "make check" on my machine.

Valerie Aurora Henson (17):
  Disable tst_refcount - doesn't compile, don't know why
  Squash warnings
  Add 64-bit bitops
  Implement 64-bit "bitarray" bmap ops
  Convert libext2fs to 64-bit bitmap interface
  Convert mke2fs to new bitmap interface
  Convert e2fsck to new bitmap interface
  Turn on new bitmaps in e2fsck and mke2fs
  Add progress bar for allocating block tables - takes forever on large
  signed int -> blk64_t to fix bugs at 2^31 - 2^32 blocks
  Fix overflow in calculation of total file system blocks
  Add ext2fs_block_iterate3 (from Ted)
  Support 48-bit file acl blocks
  super->s_*_blocks_count -> ext2fs_*_blocks_count()
  Convert to inode/block/bitmap/table loc()/loc_set() functions
  ext2fs_block_alloc_stats -> ext2fs_block_alloc_stats2
  Convert to 64-bit IO
