[PATCH] Progs: update convert for uninitialized block groups
Hello,
There is a new feature ''uninitialized block groups'' in ext4.
Block and inode bitmaps in uninitialized block groups are
uninitialized. This confuses the converter. The fix is call
ext2fs_new_inode for each block group at open time. It set
up uninitialized block and inode bitmaps appropriately.
This patch also contains some other minor fixes. Thank you,

[PATCH nbdkit 0/4] New plugin: Add linuxdisk plugin.
Turns out Japanese trains are good for coding!
In supermin we have a bunch of code to create the libguestfs
appliance. It creates it directly using libext2fs (part of
e2fsprogs). We can use the same technique to create ext2 virtual
disks in nbdkit, which is what this new plugin does. Why a new plugin
instead of modifying the floppy plugin? See the 4/4 commit message
for an explanation.

[PATCH nbdkit v2 0/5] Add linuxdisk plugin.
Another interesting thing you can do with this plugin:
https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/
v2:
- Fix inconsistent tab/space.
- All 3 plugins now contain a block of text pointing to the
other 2 plugins.
- TMDIR -> TMPDIR
- Unlink the temporary file and other cleanups along error paths.
- fclose -> pclose, and check the return value for errors.

[PATCH 0/8] extlinux: support unmounted ext2/3/4 filesystem
Hello syslinux,
Merry Christmas! These patches will make extlinux work with umounted
ext2/3/4 filesystem, for example:
$ extlinux -i /dev/sdXN
or
$ extlinux -i file_block
Also it can work with something like:
$ extlinux /dev/sdXN --reset-adv
or
$ extlinux file_block --reset-adv
We don't use a new option (I planed to use "-d" but it is already in
use), it will check whether the

[PATCH 0/9] linux/syslinux: support ext2/3/4 device
Hello,
Happy New Year!
These patches make syslinux/linux support ext2/3/4, and it doesn't
require the root privilege, I'd like to add a separate e2fs/syslinux, if
that is more appropriate, it should be easy to do that.
I put these patches on github so that you can easily get them in case
you'd like to test them. (The repo's name is sys_tmp, which avoids
confusing others, I will
