Hi Jens,
Here are 12 patchs for bcache fixes and updates, most of them were posted
by Eric Wheeler in 4.13 merge window, but delayed due to lack of code
review.
Next time, please send this _before_ the merge window opens. Not a huge
problem for this series, since it has been posted numerous times in the
past and already has good review coverage, but it really should have
been in linux-next for a week or two before heading upstream.
Hi Jens,
Copied, send patches _before_ merge window opens.
But could you please to give me a hint, how can I find when a specific
merge window will open ? I search LKML, and see people send pull
requests for 4.14 merge window, but I don't see any announcement for
4.14 merge window time slot.
The merge window opens when Linus releases the previous kernel. So you
have to try and keep track of when he expects to do that. That really
isn't that difficult - Linus always cuts a release on Sundays. We always
have 7 or 8 rc releases, so a good time to check is his mail on -rc6 or
-rc7 release, that usually gives a good indication of when he expects to
release the final.
To keep things simple, if you always have things ready when -rc7 is
released, then you are at least one week out from the merge window,
possibly two if we end up doing an -rc8. That means you don't have to
track anything, you know the exact date of when -rc7 is released since
Linus's schedule is usually reliable.
Hi Jens,
Copied, I will follow the above rule in next cycle.
And I just post the last patch
(0013-bcache-initialize-stripe_sectors_dirty-correctly-for.patch) to you
for 4.14 cycle.
This patch is an important fix for bcache writeback rate calculation, it
is depended by another patch I sent to you
(0006-bcache-correct-cache_dirty_target-in-__update_writeb.patch),
please have it in 4.14.
Thanks in advance.
Hello Jens,
FWIW I'd like to support Coly by reporting that patches 0001, 0002, 0006
and 0013 (the last one mentioned above) have been tested by me on 2
production servers with a good deal of bcache activity for the last 6
weeks without any issues having arisen.
But this may not be much use to you to know, as these are running
vanilla kernel.org kernel 4.4.77. Still, these 4 patches exactly as
Coly has sent them to you apply without any changes to the code, so I
guess it vouches for the code at least somewhat.
Eddie
