That is roughly right; more details are here: https://www.kernel.org/doc/html/latest/process/2.Process.html#next-trees Most of it is still correct; some of it might be outdated. E.g., I am not completely sure if Andrew Morton still does this mentioned in the documentation: "The -mm tree integrates patches from a long list of subsystem trees", or if most integration from a long list of subsystem trees is nowadays completely done by Stephen Rothwell in linux-next. Also, possibly the statistics is outdated here in this statement: "In a typical development cycle, approximately 5-10% of the patches going into the mainline get there via -mm." One might need to check the current numbers and update the percentage here. Feel free to do a bit more research if you are interested and send a patch to update the Documentation on what you learned.

Good own investigation so far.
The patch you point out is already applied to a maintainer's (Mauro's)
integration tree, and hence in linux-next:
commit 05344a1d2ea7bad3492c34299c37407bfcfed355
Author: Arnd Bergmann
Date: Mon Aug 2 16:38:14 2021 +0200
media: atomisp: restore missing 'return' statement
The input_system_configure_channel_sensor() function lost its final
return code in a previous patch:
drivers/staging/media/atomisp/pci/hive_isp_css_common/host/input_system.c:
In function 'input_system_configure_channel_sensor':
drivers/staging/media/atomisp/pci/hive_isp_css_common/host/input_system.c:1649:1:
error: control reaches end of non-void function [-Werror=return-type]
Restore what was there originally.

Fixes: 728a5c64ae5f ("media: atomisp: remove dublicate code")
Signed-off-by: Arnd Bergmann
Acked-by: Sakari Ailus
Signed-off-by: Mauro Carvalho Chehab
So, it is just a matter of hours until Linus takes the pull request
from Mauro, v5.15-rc1 is out and the issue is resolved. If you ping
Greg with this patch being good for stable, he will pick it and
probably apply that for the v5.14 stable tree as well.
So be a bit patient, or change your config... Do you really need this
driver? Is it really important to you and your business? Then,
consider that it is currently under drivers/staging/ and might just
disappear from one day to another because nobody is aware of critical
users (that is why it is in staging in the first place).
I hope this helps,
Lukas

I tried to build the latest source code available in master. Judging by the latest tag name it's v5.14-rc7. When pulling for new changes with git pull there was "Already up to date" message.

Kernel upstream compile error at drivers/staging/media
Hello! I'm learning the Linux Kernel and currently faced troubles with building the upstream. I git clone'd source code of master and tried to make deb-pkg. I faced compile error: drivers/staging/media/atomisp/pci/hive_isp_css_common/host/input_system.c: In function ‘input_system_configure_channel_sensor’: drivers/staging/media/atomisp/pci/hive_isp_css_common/host/input_system.c:1649:1: error: control reaches end of non-void function [-Werror=return-type] 1649 | } What this error could be about and how to fix it? Maybe some wrong compilation flag is the cause? Thank you!___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

That is quite old, 5.14 was released on August 29, and there have been 9718 changes added to the tree since then. > When pulling for new changes with git pull there was "Already up to date" > message.
