Disabling the adapter after each transfer is pretty bad for sensors and
other devices doing small transfers at a high rate. It slows down the
transfer rate a lot since each of them have to wait the adapter to be
enabled again.
During the transfer init we check the status register for no activity

The OUT1 and OUT2 pins present on some legacy UARTs are basically GPIOs.
It doesn't make much sense to emulate GPIOs using other GPIOs, hence
drop support for that.

Ah
In order to support mounts from namespaces other than
init_user_ns, fuse must translate uids and gids to/from the

patch does that, with a couple of restrictions on the namespace:
- The userns for the fuse connection is fixed to the names

Goal of this patch is to use the new libnl API to align netlink attribute
when needed.
The layout of the netlink message will be a bit different after the patch,
because the padattr (TASKSTATS_TYPE_STATS) will be inside the nested
attribute instead of before it.

This is the continuation of the work done to align netlink attributes
when these attributes contain some 64-bit fields.
David, if the third patch is too big (or maybe the series), I can split it.

In a userns mount some on-disk inodes may have ids which do not
map into s_user_ns, in which case the in-kernel inodes are owned
by invalid users. The superblock owner should be able to change

Security labels from unprivileged mounts in user namespaces must
be ignored. Force superblocks from user namespaces whose labeling
behavior is to use xattrs to use mountpoint labeling instead.
