Subject: [PATCH 4/4] debugfs: fix printing of xattrs with ea_in_inode values
Due to a missing "else" debugfs was printing (garbage) from the xattr
buffer which could potentially overrun the end of the buffer.

Subject: [PATCH 2/4] debugfs: fix set_inode_field so it can set the checksum
field
Previously, setting the inode field was a no-op, since the library
function ext2fs_write_inode_full() would override whatever value was
set by debugfs. Use the new ext2fs_write_inode2() interface so we can
in fact set the checksum to a potentially wrong value. Also, ignore
the inode checksum failures if we are setting the checksum, and if the
checksum value is "calc", set the inode checksum to the correct value.

Subject: [PATCH 3/4] e2fsck: check and fix tails of all bitmap blocks
Currently, e2fsck effectively checks only tail of the last inode and
block bitmap in the filesystem. Thus if some previous bitmap has unset
bits it goes unnoticed. Mostly these tail bits in the bitmap are
ignored; however, if blocks_per_group are smaller than 8*blocksize,
the multi-block allocator in the kernel can get confused when the tail
bits are unset and return bogus free extent.
Add support to libext2fs to check these bitmap tails when loading
bitmaps (as that's about the only place which has access to the bitmap
tail bits) and make e2fsck use this functionality to detect buggy bitmap
tails and fix them (by rewriting the bitmaps).

Subject: [PATCH 3/4] e2image: add -b and -B options to specify where to find
the superblock
e2image has no ability to use superblock backup to copy metadata.
This feature can be useful if someone wants to make partition
image and fix it using e2fsck utility.
New -b option allows to pass superblock number, like e2fsck utility does.
e2image doesn't change primary superblock and store it as is, so
it can be fixed using e2fsck latter. Option -B allows setting
superblock size.

Add new library interface which allows the caller to control whether
the inode checksum should be checked on inode read, or set on inode
write.

Subject: [PATCH] mke2fs: accept the english yes character to the proceed
question
In some cases if the translation file is missing some translations,
mke2fs can end up printing an English message, e.g.:
% LANG=it_IT.UTF-8 ./mke2fs /tmp/foo.img 8M
mke2fs 1.45.1 (12-May-2019)
/tmp/foo.img contiene un file system ext4
created on Mon May 27 19:35:48 2019
Proceed anyway? (y,N)
However, if there is a translation for string to match with "yY"
(e.g., to "sS" for Italian), then 'y' won't work. Fix this by falling
back to the english 'yY' characters.
