The admin guide is a good start, but it's time to turn it into something
better than an unordered blob of files. This is a first step in that
direction. The TOC has been split up and annotated, the guides have been
reordered, and minor tweaks have been applied to a few of them.
One consequence of splitting up the TOC is that we don't really want to use
:numbered: anymore, since the count resets every time and there doesn't
seem to be a way to change that. Eventually we probably want to group the
documents into sub-books, at which point we can go back to a single TOC,
but it's probably early to do that.

fs/super.c: fix race between freeze_super() and thaw_super()
Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than
frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which
drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering.
In this case thaw_super() will wrongly call s_op->unfreeze_fs() before
it was actually frozen, and call sb_freeze_unlock() which leads to the
unbalanced percpu_up_write(). Unfortunately lockdep can't detect this,

The caller may have to check whether these functions actually used
the provided buffer or allocated a new one -- but this differs between
the too. Let's just add a kernel doc to clarify what the semantics are
for each function.

This does bring a regression, because genksyms no longer generates

working on a patch to fix this.
Plus, we are talking about functions like strcpy(), which rarely
change prototypes.

Pull rdma qedr RoCE driver from Doug Ledford:
"Early on in the merge window I mentioned I had a backlog of new
drivers waiting to be reviewed and that, in addition to the hns-roce
driver, I wanted to get possible a couple more reviewed. I ended up
only having the time to complete one of the additional drivers.
During Dave Miller's pull request this go around, there were a series
of 9 patches to the QLogic qed net driver that add basic support for a
paired RoCE driver. That support is currently not functional because
it is missing the matching RoCE driver in the RDMA subsystem. I
managed to finish that review. However, because it goes against part
of Dave's net pull, and a part that was accepted a day or two after
the merge window opened, to apply cleanly it has to be applied to
either the tip of Dave's net branch, or as I did in this case, I just
applied it to your master after you had taken Dave's pull request."

"This merge window was the first where Huawei had to try and coordinate
their patches between their net driver and their new roce driver
(similar to mlx4 and mlx5).
They didn't do horribly, but there were some issues (and we knew that
because they simply didn't know what to do in the beginning). As a
result, I had a set of patches that depended on some patches that
normally would have come to you via Dave's tree. Those patches have
been on netdev@ for a while, so I got Dave to give me his approval to
send them to you. As such, the other 29 patches I had behind them are
also now ready to go.
This catches the hns and hns-roce drivers up to current, and for
future patches we are working with them to get them up to speed on how
to do joint driver development so that they don't have these sorts of
cross tree dependency issues again. BTW, Dave gave me permission to
add his Acked-by: to the patches against the net tree, but I've had
this branch through 0day (but not linux-next since it was off by
itself) and I didn't want to rebase the series just to add Dave's ack
for the 8 patches in the net area.
Updates to the hns drivers:
- Small patch set for hns net driver that the roce patches depend on
- Various fixes to the hns-roce driver
- Add connection manager support to the hns-roce driver"
