The ulist @qgroups is utilized to record all involved qgroups from both
old and new roots inside btrfs_qgroup_account_extent().

Due to the fact that qgroup_update_refcnt() itself is already utilizing
qgroup_iterator, here we have to introduce another list_head,
btrfs_qgroup::nested_iterator, allowing nested iteration.

For function qgroup_update_refcnt(), we use @tmp list to iterate all the
involved qgroups of a subvolume.

It's a perfect match for qgroup_iterator facility, as that @tmp ulist
has a very limited lifespan (just inside the while() loop).

By migrating to qgroup_iterator, we can get rid of the GFP_ATOMIC memory
allocation and no error handling is needed.

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.

Static calls invocations aren't well supported from module __init and
__exit functions. Especially the static call from cleanup_trusted() led
to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y.

However, the usage of static call invocations for trusted_key_init()
and trusted_key_exit() don't add any value from either a performance or
security perspective. Hence switch to use indirect function calls instead.

Note here that although it will fix the current crash report, ultimately
the static call infrastructure should be fixed to either support its
future usage from module __init and __exit functions or not.

device is in the running state without checking if the device request
queue (in the case of block device) is also running, thus allowing the
exectuion of internal requests. Without checking the device request
queue, commit ff48b378 fix is incomplete and deadlocks on resume can
still happen. Use blk_queue_pm_only() to check if the device request
queue allows executing commands in addition to checking the SCSI device

Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig

The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.
