That went into the tree back in 2005; the comment used to be true for
predecessor of simple_fill_super() that happened to live in nfsd; that one
didn't take care to skip the array entries with NULL ->name, so it could
not tolerate any gaps. That had been fixed in 2003 when nfsd_fill_super()
had been abstracted into simple_fill_super(); if Neil's patch lived out
of tree during that time, he probably replaced the name of function when
rebasing it and didn't notice that restriction in question was no longer
there.

First of all, any dentry getting here would have passed bfs_lookup(),
so it it passed ENAMETOOLONG check there, there's no need to
repeat it. And we are not going to get dentries with zero name length -
that check ultimately comes from ext2 and it's as pointless here as it
used to be there.

When no timer is queued into an empty timer base, the next_expiry will not
be updated. It was originally calculated as
base->clk + NEXT_TIMER_MAX_DELTA
When the timer base stays empty long enough (> NEXT_TIMER_MAX_DELTA), the
next_expiry value of the empty base suggests that there is a timer pending
soon. This might be more a kind of a theoretical problem, but the fix
doesn't hurt.
Use only base->next_expiry value as nextevt when timers are
pending. Otherwise nextevt will be jiffies + NEXT_TIMER_MAX_DELTA. As all
information is in place, update base->next_expiry value of the empty timer
base as well.

To improve readability of the code, split base->idle calculation and
expires calculation into separate parts. While at it, update the comment
about timer base idle marking.
Thereby the following subtle change happens if the next event is just one
jiffy ahead and the tick was already stopped: Originally base->is_idle
remains true in this situation. Now base->is_idle turns to false. This may
spare an IPI if a timer is enqueued remotely to an idle CPU that is going
to tick on the next jiffy.

Forwarding timer base is done when the next expiry value is calculated and
when a new timer is enqueued. When the next expiry value is calculated the
jiffies value is already available and does not need to be reread a second
time.

The current check whether a forward of the timer base is required can be
simplified by using an already existing comparison function which is easier
to read. The related comment is outdated and was not updated when the check
changed in commit 36cd28a4cdd0 ("timers: Lower base clock forwarding
threshold").
Use time_before_eq() for the check and replace the comment by copying the
comment from the same check inside get_next_timer_interrupt(). Move the
precious information of the outdated comment to the proper place in
__run_timers().

Deferrable timers do not prevent CPU from going idle and are not taken into

For starting a timer, the timer is enqueued into a bucket of the timer
wheel. The bucket expiry is the defacto expiry of the timer but it is not
equal the timer expiry because of increasing granularity when bucket is in
a higher level of the wheel. To be able to figure out in a trace whether a
timer expired in time or not, the bucket expiry time is required as well.
Add bucket expiry time to the timer_start tracepoint and thereby simplify
the arguments.

When the next tick is in the past, the delta between basemono and the next
tick gets negativ. But the next tick should never be in the past. The
negative effect of a wrong next tick might be a stop of the tick and timers
might expire late.
To prevent expensive debugging when changing underlying code, add a
WARN_ON_ONCE into this code path. To prevent complete misbehaviour, also
reset next_tick to basemono in this case.

Some PWM devices require sleeping, for example if the pwm device is
connected over I2C. However, many PWM devices could be used from atomic
context, e.g. memory mapped PWM. This is useful for, for example, the
pwm-ir-tx driver which requires precise timing. Sleeping causes havoc
with the generated IR signal.
Since not all PWM devices can support atomic context, we also add a
pwm_might_sleep() function to check if is not supported.
