The map_to_7segment.h provides generic 7segment LED mappings and is
designed to be used by other drivers. Moving it to common area will
make it more usable. Also exporting it to userspace will help users

If the journal doesn't abort when it gets an IO error in file data
blocks, the file data corruption will spread silently. Because
most of applications and commands do buffered writes without fsync(),
they don't notice the IO error. It's scary for mission critical
systems. On the other hand, if the journal aborts whenever it gets
an IO error in file data blocks, the system will easily become
inoperable. So this patch introduces a filesystem option to
determine whether it aborts the journal or just call printk() when
it gets an IO error in file data.
If you mount an ext4 fs with data_err=abort option, it aborts on file
data write error. If you mount it with data_err=ignore, it doesn't
abort, just call printk(). data_err=ignore is the default.
Here is the corresponding patch of the ext3 version:

When a checkpointing IO fails, current JBD2 code doesn't check the
error and continue journaling. This means latest metadata can be
lost from both the journal and filesystem.
This patch leaves the failed metadata blocks in the journal space
and aborts journaling in the case of jbd2_log_do_checkpoint().
To achieve this, we need to do:
1. don't remove the failed buffer from the checkpoint list where in
the case of __try_to_free_cp_buf() because it may be released or
overwritten by a later transaction
2. jbd2_log_do_checkpoint() is the last chance, remove the failed
buffer from the checkpoint list and abort the journal
3. when checkpointing fails, don't update the journal super block to
prevent the journaled contents from being cleaned. For safety,
don't update j_tail and j_tail_sequence either
4. when checkpointing fails, notify this error to the ext4 layer so
that ext4 don't clear the needs_recovery flag, otherwise the
journaled contents are ignored and cleaned in the recovery phase
5. if the recovery fails, keep the needs_recovery flag
6. prevent jbd2_cleanup_journal_tail() from being called between
__jbd2_journal_drop_transaction() and jbd2_journal_abort()
(a possible race issue between jbd2_log_do_checkpoint()s called by
jbd2_journal_flush() and __jbd2_log_wait_for_space())

We need to add a flag for all code that is in the drivers/staging/
directory to prevent all other kernel developers from worrying about
issues here, and to notify users that the drivers might not be as good
as they are normally used to.
Based on code from Andreas Gruenbacher and Jeff Mahoney to provide a
TAINT flag for the support level of a kernel module in the Novell
enterprise kernel release.
This is the kernel portion of this feature, the ability for the flag to
be set needs to be done in the build process and will happen in a
follow-up patch.

After rework settings will be no longer created dynamically
for each device so we need to make some fixups first.
* Use set_[ksettings,unmaskirq]() as a set function for

* Allow writes to ["io_32bit","unmaskirq"] settings also when
drive->no_[io_32bit,unmask] is set (this is checked later inside
set_[io_32bit,unmaskirq]() anywyay and keeps consistency with
the corresponding HDIO_SET_[32BIT,UNMASKINTR] ioctls).
* Use max possible multi sectors value (16) as an allowed max for
"multcount" setting. set_multcount() set function checks against
device's max possbile value anyway and it makes the proc setting
