Move get_rx_bufs() to vhost.c and rename it to
vhost_get_rx_bufs(). This helps to hide vring internal layout from
specific device implementation. Packed ring implementation will

Hi all:
This RFC implement packed ring layout. The code were tested with
Tiwei's RFC V2 a thttps://lkml.org/lkml/2018/4/1/48. Some fixups and
tweaks were needed on top of Tiwei's code to make it run. TCP stream
and pktgen does not show obvious difference compared with split ring.
Changes from V2:
Instead of depending on the exported vring_used_elem, this patch
switches to use a new internal structure vhost_used_elem which embed
vring_used_elem in itself. This could be used to let vhost to record
extra metadata for the incoming packed ring layout.

With the addition of the end-of-test state, it is not uncommon for the
kvm.sh summary lines to overflow 80 characters. This commit therefore
applies abbreviations in order to make the line fit into 80 characters
with high probability.
And yes, I did make heavy use of punched cards back in the day
Currently, kvm-find-errors.sh looks only for build errors ("error:"),
so this commit makes it also locate build warnings ("warning:").

This commit adds a script that allows viewing the build and/or
console output from failed rcutorture, locktorture, or rcuperf runs.
This replaces a time-honored but inefficient manual procedure that uses
cut and paste.

This commit adds the end-of-test test, if present in the console output,
to the kvm.sh test summary that is printed by kvm-recheck.sh. Note that
this only applies to rcutorture console output.

The rcutorture scripting scans the console output twice, once to look
for various sorts of hangs and again to find warnings and panics.
Unfortunately, only the output of the second scan gets written to the
console.log.diags file, which can cause hangs to be overlooked.
This commit therefore folds t
This commit adds end-of-test state printout to help check whether RCU
shut down nicely. Note that this printout only helps for flavors of
RCU that are not used much by the kernel. In particular, for normal
RCU having a grace period in progress is expected behavior.

Hello!
This series contains torture-test updates:
1. Add a script to edit output from failed runs. Running this
script takes your editor through the build errors and the various
problems in the console output, for each such file, first showing
a summary of the errors
The __rcu_process_callbacks() function currently checks to see if
the current CPU needs a grace period and also if there is any other
reason to kick off a new grace period. This is one of the fail-safe
checks that has been rendered unnecessary by the changes that increase
the accuracy of rcu_gp_cl
The rcu_start_future_gp() function uses a sloppy check for a grace
period being in progress, which works today because there are a number
of code sequences that resolve the resulting races. However, some of
these race-resolution code sequences must acquire the root rcu_node
structure's ->lock, and
Hi Greg,
Today's linux-next merge of the usb tree got a conflict in:

The rcu_migrate_callbacks() function invokes rcu_advance_cbs()
twice, ignoring the return value. This is OK at pressent because of
failsafe code that does the wakeup when needed. However, this failsafe
code acquires the root rcu_node structure's lock frequently, while
rcu_migrate_callbacks() does
There is no longer any need for ->need_future_gp[] to count the number of
requests for future grace periods, so this commit converts the additions
to assignments to "true" and reduces the size of each element to one byte.
While we are in the area, fix an obsolete comment.

Accessors for the ->need_future_gp[] array are currently open-coded,
which makes them difficult to change. To improve maintainability, this

Currently, the rcu_future_needs_gp() function checks only the current
element of the ->need_future_gps[] array, which might miss elements that
were offset from the expected element, for example, due to races with
the start or the end of a grace period. This commit therefore makes

The rcu_start_gp_advanced() is invoked only from rcu_start_future_gp() and
much of its code is redundant when invoked from that context. This commit
therefore inlines rcu_start_gp_advanced() into rcu_start_future_gp(),
then removes rcu_start_gp_advanced().

Currently, rcu_gp_cleanup() scans the rcu_node tree in order to reset
state to reflect the end of the grace period. It also checks to see
whether a new grace period is needed, but in a number of cases, rather
than directly cause the new grace period to be immediately started, it
instead leaves the
When rcu_cbs_completed() is invoked on a non-root rcu_node structure,
it unconditionally assumes that two grace periods must complete before
the callbacks at hand can be invoked. This is overly conservative because
if that non-root rcu_node structure believes that no grace period is in
progress, a
It is true that currently only the low-order two bits are used, so
there should be no problem given modern machines and compilers, but
good hygiene and maintainability dictates use of an unsigned long
instead of an int. This commit therefore makes this change.

Once the grace period has ended, any RCU_GP_FLAG_FQS requests are
irrelevant: The grace period has ended, so there is no longer any
point in forcing quiescent states in order to try to make it end sooner.

All of the cpu_needs_another_gp() function's checks (except for
newly arrived callbacks) have been subsumed into the rcu_gp_cleanup()
function's scan of the rcu_node tree. This commit therefore drops the
call to cpu_needs_another_gp(). The check for newly arrived callbacks
is supplied by rcu_acce
Now that grace-period requests use funnel locking and now that they

kthread has not yet started, rcu_gp_kthread() no longer needs to check
need_any_future_gp() at startup time. This commit therefore removes
this check.

If rcu_start_this_gp() is invoked with a requested grace period more
than three in the future, then either the ->need_future_gp[] array
needs to be bigger or the caller needs to be repaired. This commit
therefore adds a WARN_ON_ONCE() checking for this condition.

The rcu_cbs_completed() function provides the value of ->completed
at which new callbacks can safely be invoked. This is recorded in
two-element ->need_future_gp[] arrays in the rcu_node structure, and
the elements of these arrays corresponding to the just-completed grace
period are zeroed at the
