Qgroup heavily relies on ulist to go through all the involved
qgroups, but since we're using ulist inside fs_info->qgroup_lock
spinlock, this means we're doing a lot of GFP_ATOMIC allocations.
This patch reduces the GFP_ATOMIC usage for qgroup_reserve() by
eliminating the memory allocation completely.
This is done by moving the needed memory to btrfs_qgroup::iterator
list_head, so that we can put all the involved qgroup into a on-stack
list, thus eliminating the need to allocate memory while holding
spinlock.
The only cost is the slightly higher memory usage, but considering the
reduce GFP_ATOMIC during a hot path, it should still be acceptable.
Function qgroup_reserve() is the perfect start point for this
conversion.

The flag EXTENT_NOWAIT is a special flag to notify extent-io-tree code
that this operation should not sleep for the extent state preallocation.
However for btrfs_redirty_list_add(), all callers are able to sleep:
- clean_log_buffer()
Just 2 lines before, we call btrfs_pin_reserved_extent(), which calls
pin_down_extent(), and that function does not require EXTENT_NOWAIT.
Thus we're safe to call it without EXTENT_NOWAIT.
- btrfs_free_tree_block()
This function have several call sites which trigger tree read, e.g.
walk_up_proc(), thus we're safe to call it without EXTENT_NOWAIT.
Thus there is no need to require EXTENT_NOWAIT flag.

Among all the callers, only the device_list_add() function uses the
second argument of alloc_fs_devices(). It passes metadata_uuid when
available, otherwise, it passes NULL. And in turn, alloc_fs_devices()
is designed to copy either metadata_uuid or fsid into
fs_devices::metadata_uuid.
So remove the second argument in alloc_fs_devices(), and always copy the
fsid. In the caller device_list_add() function, we will overwrite it
with metadata_uuid when it is available.

There have been instances when the default size (1M) of the STB is not
sufficient to get the complete traces of the failure. In such scenarios
we can use a module_param to enable full trace that shall contain more
debugging data. This is not a regular case and hence not enabling this
capability by default.
With this change, there will be two cases on how the driver fetches the
stb data:
1) A special case (proposed now) - which is required only for certain
platforms. Here, a new module param will be supplied to the driver that
will have a special PMFW supporting enhanced dram sizes for getting
the stb data. Without the special PMFW support, just setting the module
param will not help to get the enhanced stb data.
To adapt to this change, we will have a new amd_pmc_stb_handle_efr() to
handle enhanced firmware reporting mechanism. Note that, since num_samples
based r/w pointer offset calculation is not required for enhanced firmware
reporting we will have this mailbox command sent only in case of regular
STB cases.
2) Current code branch which fetches the stb data based on the parameters
like the num_samples, fsize and the r/w pointer.

In amd_pmc_stb_debugfs_open_v2(), the stb buffer is created based on the
num_samples and the read/write pointer offset. This holds good when the
num_samples reported by PMFW is less than S2D_TELEMETRY_BYTES_MAX; where
the stb buffer gets filled from 0th position until
S2D_TELEMETRY_BYTES_MAX - 1 based on the read/write pointer offset.
But when the num_samples exceeds the S2D_TELEMETRY_BYTES_MAX, the current
code does not handle it well as it does not account for the cases where
the stb buffer has to filled up as a circular buffer.
Handle this scenario into two cases, where first memcpy will have the
samples from location:
(num_samples % S2D_TELEMETRY_BYTES_MAX) - (S2D_TELEMETRY_BYTES_MAX - 1)
and next memcpy will have the newest ones i.e.
0 - (num_samples % S2D_TELEMETRY_BYTES_MAX - 1)
