[PATCH 0/4 v3] e2fsprogs journal fixes (UUID and 1k block size issue)

[Azat Khuzhin <a3at.mail@gmail.com>]

Hi all,

Here is patchset with some fixes for journal code in e2fsprogs.
I've removed first patch from previous version "lib: add EXT2_ prefix for
SUPERBLOCK_{OFFSET,SIZE}", and rebase other patches on top of the maint branch.

I've tested it using "make check" and commands from commits.
I do want to add tests for this cases, but they requires some extra
capabilities (CAP_SYS_ADMIN for mount(2)), while right now tests don't have
such cases, if somebody have proposal how to do this tests without extra
mount(2) I will be happy to hear (for more info about possible test cases see
"tune2fs: update journal super block when changing UUID for fs." and "tune2fs:
update journal users while updating fs UUID (with external journal)")

Thanks.
Azat.

Azat Khuzhin (4):
  journal: use consts instead of 1024 and add helper for journal with 1k
    blocksize
  tune2fs: remove_journal_device(): use the correct block to find jsb
  tune2fs: update journal super block when changing UUID for fs.
  tune2fs: update journal users while updating fs UUID (with external
    journal)
