Hi Jason

It is normal to include after the --- what you have changed since the
previous version.

I ran checkpatch on this again.

Last time, we had:

total: 6 errors, 763 warnings, 6514 lines checked

This time, we have:

total: 8 errors, 196 warnings, 7470 lines checked

So much better with the warnings. Thanks.

The errors should be simple to fix:

ERROR: that open brace { should be on the previous line
ERROR: that open brace { should be on the previous line
ERROR: spaces required around that '=' (ctx:VxW)
ERROR: spaces required around that '=' (ctx:VxW)
ERROR: spaces required around that '=' (ctx:VxW)
ERROR: that open brace { should be on the previous line
ERROR: Use of __initconst requires a separate use of const
ERROR: trailing whitespace

One appears to be a false positive:

+static const struct {
+       bool result;
+       unsigned int msec_to_sleep_before;
+} expected_results[] __initconst = {
+       [0 ... PACKETS_BURSTABLE - 1] = { true, 0 },
+       [PACKETS_BURSTABLE] = { false, 0 },
+       [PACKETS_BURSTABLE + 1] = { true, MSEC_PER_SEC / PACKETS_PER_SECOND },
+       [PACKETS_BURSTABLE + 2] = { false, 0 },
+       [PACKETS_BURSTABLE + 3] = { true, (MSEC_PER_SEC / PACKETS_PER_SECOND) * 2 },
+       [PACKETS_BURSTABLE + 4] = { true, 0 },
+       [PACKETS_BURSTABLE + 5] = { false, 0 }
+};

Looking at some of the warnings:

are not very nice.

kcalloc and friends are pretty noisy when they fails. No need to add
your own print.

I see we still have a lot of __always_inline in C files :-(
