ext4: add an option to control error handling on file data
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:

jbd2: don't dirty original metadata buffer on abort
Currently, original metadata buffers are dirtied when they are
unfiled whether the journal has aborted or not. Eventually these
buffers will be written-back to the filesystem by pdflush. This
means some metadata buffers are written to the filesystem without
journaling if the journal aborts. So if both journal abort and
system crash happen at the same time, the filesystem would become
inconsistent state. Additionally, replaying journaled metadata
can overwrite the latest metadata on the filesystem partly.
Because, if the journal gets aborted, journaled metadata are
preserved and replayed during the next mount not to lose
uncheckpointed metadata. This would also break the consistency
of the filesystem.
This patch prevents original metadata buffers from being dirtied
on abort by clearing BH_JBDDirty flag from those buffers. Thus,
no metadata buffers are written to the filesystem without journaling.

ext4: add checks for errors from jbd2
If the journal has aborted due to a checkpointing failure, we
have to keep the contents of the journal space. Otherwise, the
filesystem will lose uncheckpointed metadata completely and
become inconsistent. To avoid this, we need to keep needs_recovery
flag if checkpoint has failed.
With this patch, ext4_put_super() detects a checkpointing failure
from the return value of journal_destroy(), then it invokes
ext4_abort() to make the filesystem read only and keep
needs_recovery flag. Errors from jbd2_journal_flush() are also
handled by this patch in some places.

jbd2: fix error handling for checkpoint io
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())

jbd2: abort when failed to log metadata buffers
If we failed to write metadata buffers to the journal space and
succeeded to write the commit record, stale data can be written
back to the filesystem as metadata in the recovery phase.
To avoid this, when we failed to write out metadata buffers,
abort the journal before writing the commit record.
We can also avoid this kind of corruption by using the journal
checksum feature because it can detect invalid metadata blocks in the
journal and avoid them from being replayed. So we don't need to care
about asynchronous commit record writeout with a checksum.

r8169: make room for more specific 8168 hardware start procedure
Broadly speaking the 8168c* share some common code which will
be factored in __rtl_hw_start_8168cp. The 8168b* share some
code too but it will be a bit different.
Any change of behavior should be confined to the currently
unidentified 8168 chipsets. They will not be applied the Tx
performance tweak and will emit a warning instead.

r8169: shuffle some registers handling around (8168 operation only)
I can not argue strongly for (or against) a specific ordering
on a purely technical ground but the patch avoids to swallow
Realtek's changes in one big, hard-to-read gulp.
Let aside the way the RxConfig register is written (see
rtl_set_rx_tx_config_registers / RxConfig / rtl_set_rx_mode),
this change brings the registers write ordering closer with
Realtek's driver one (version 8.006.00) for the 8168 chipsets.
More 8168 specific code which touches the Configx registers will
be added in the section covered by Cfg9346_UnLock / Cfg9346_Lock.
This code should not be the cause of regression for 810x and
8110 users.
