2132b71f78 net/mlx5e: Advertise globaly supported FEC modes 
Ethtool advertise supported link modes on an interface. Per each FEC
mode, query if there is a link type which supports it. If so, add this
FEC mode to the supported FEC modes list. Prior to this patch, ethtool
advertised only the supported FEC modes on the current link type.
Add an explicit mapping between internal FEC modes and ethtool link mode
bits. With this change, adding new FEC modes in the downstream patch
would be easier.

4bd9d5070b net/mlx5e: Enforce setting of a single FEC mode 
Ethtool command allow setting of several FEC modes in a single set
command. The driver can only set a single FEC mode at a time. With this
patch driver will reply not-supported on setting several FEC modes.

511aa2aa63 net/mlx5e: Set FEC to auto when configured mode is not supported 
When configuring FEC mode, driver tries to set it for all available
link types. If a link type doesn't support a FEC mode, set this link
type to auto (FW best effort). Prior to this patch, when a link type
didn't support a FEC mode is was set to no FEC.

b21aef7e71 mlx5: Use proper logging and tracing line terminations 
netdev_err should use newline termination but mlx5_health_report
is used in a trace output function devlink_health_report where
no newline should be used.

Remove the newlines from a couple formats and add a format string
of "%s\n" to the netdev_err call to not directly output the
logging string.

Also use snprintf to avoid any possible output string overrun.

0f56d3c5d8 net/mlx5e: Support dump callback in RX reporter 
Add support for SQ's FW dump on RX reporter's events. Use Resource dump
API to retrieve the relevant data: RX slice, RQ dump, RX buffer and
ICOSQ dump (depends on the error). Wrap it in formatted messages and
store the binary output in devlink core.

12206b1723 net/mlx5: Add support for resource dump 
On driver load:
- Initialize resource dump data structure and memory access tools (mkey
  & pd).
- Read the resource dump's menu which contains the FW segment
  identifier. Each record is identified by the segment name (ASCII).

During the driver's course of life, users (like reporters) may request
dumps per segment. The user should create a command providing the
segment identifier (SW enumeration) and command keys. In return, the
user receives a command context. In order to receive the dump, the user
should supply the command context and a memory (aligned to a PAGE) on
which the dump content will be written. Since the dump may be larger
than the given memory, the user may resubmit the command until received
an indication of end-of-dump. It is the user's responsibility to destroy
the command.

e75fd33b3f Btrfs: fix btrfs_wait_ordered_range() so that it waits for all ordered extents 
In btrfs_wait_ordered_range() once we find an ordered extent that has
finished with an error we exit the loop and don't wait for any other
ordered extents that might be still in progress.

All the users of btrfs_wait_ordered_range() expect that there are no more
ordered extents in progress after that function returns. So past fixes
such like the ones from the two following commits:

  ff612ba784 ("btrfs: fix panic during relocation after ENOSPC before
                   writeback happens")

  28aeeac1dd ("Btrfs: fix panic when starting bg cache writeout after
                   IO error")

don't work when there are multiple ordered extents in the range.

Fix that by making btrfs_wait_ordered_range() wait for all ordered extents
even after it finds one that had an error.

  ? do_syscall_64+0x5b/0x1b0
  ? entry_SYSCALL_64_after_hwframe+0x44/0xa9

This happens if we fail to insert our reserved file extent.  At this
point we've already converted our reservation from ->bytes_may_use to
->bytes_reserved.  However once we break we will attempt to free
everything from [cur_offset, end] from ->bytes_may_use, but our extent
reservation will overlap part of this.

Fix this problem by adding ins.offset (our extent allocation size) to
cur_offset so we remove the actual remaining part from ->bytes_may_use.

I validated this fix using my inject-error.py script

python inject-error.py -o should_fail_bio -t cache_save_setup -t \
	__btrfs_prealloc_file_range \
	-t insert_reserved_file_extent.constprop.0 \
	-r "-5" ./run-fsstress.sh

where run-fsstress.sh simply mounts and runs fsstress on a disk.

bd727173e4 btrfs: handle logged extent failure properly 
If we're allocating a logged extent we attempt to insert an extent
record for the file extent directly.  We increase
space_info->bytes_reserved, because the extent entry addition will call
btrfs_update_block_group(), which will convert the ->bytes_reserved to
->bytes_used.  However if we fail at any point while inserting the
extent entry we will bail and leave space on ->bytes_reserved, which
will trigger a WARN_ON() on umount.  Fix this by pinning the space if we
fail to insert, which is what happens in every other failure case that
involves adding the extent entry.

 		ASoC: soc-pcm: use goto and remove multi return 
When we use some kind of lock, we need to do unlock.
In that time, multi unlock/return is not good implementation.
This patch add label and use goto at dpcm_fe_dai_open()
to reduce such code.

 		ASoC: soc-pcm: add snd_soc_dpcm_can_be() and remove duplicate code 
Below functions are doing very similar things, the difference is
used state only.

	snd_soc_dpcm_can_be_free_stop()
	snd_soc_dpcm_can_be_params()

This patch adds common snd_soc_dpcm_check_state(), and use it from
snd_soc_dpcm_can_be_free_stop() / snd_soc_dpcm_can_be_params().
It can reduce duplicate code.

If it exists only by assumption that "it may be necessary someday",

 		ASoC: soc-pcm: use dai_get_widget() at dpcm_end_walk_at_be() 
dpcm_end_walk_at_be() has very duplicate code.

	dpcm_end_walk_at_be() {
		...
		if (stream == SNDRV_PCM_STREAM_PLAYBACK) {
(1)			/* code for Playback */
		} else  {
(2)			/* code for Capture */
		}
	}

The difference between Playback (1) and Capture (2) code is pointer only
(= "playback_widget" or "caputre_widget").
OTOH, now we already has dai_get_widget() for it.
This means we can merge (1) and (2).
This patch do it and remove duplicated code.

1e90315149 btrfs: do not check delayed items are empty for single transaction cleanup 
btrfs_assert_delayed_root_empty() will check if the delayed root is
completely empty, but this is a filesystem-wide check.  On cleanup we
may have allowed other transactions to begin, for whatever reason, and
thus the delayed root is not empty.

So remove this check from cleanup_one_transation().  This however can
stay in btrfs_cleanup_transaction(), because it checks only after all of
the transactions have been properly cleaned up, and thus is valid.

315bf8ef91 btrfs: reset fs_root to NULL on error in open_ctree 
While running my error injection script I hit a panic when we tried to
clean up the fs_root when freeing the fs_root.  This is because
fs_info->fs_root == PTR_ERR(-EIO), which isn't great.  Fix this by
setting fs_info->fs_root = NULL; if we fail to read the root.

81f7eb00ff btrfs: destroy qgroup extent records on transaction abort 
We clean up the delayed references when we abort a transaction but we
leave the pending qgroup extent records behind, leaking memory.

This patch destroys the extent records when we destroy the delayed refs
and makes sure ensure they're gone before releasing the transaction.
