You should never rebase a public-facing branch

Linus found this issue by check commit time of commits, but I also found so
many commit in mainline are too young to be merged into linux-next before
Hi,
Frequently, I found Stephen Rothwell send email about he have created
today's linux-next tree.
On the other hand, the maintainer sometimes write their pull request
like "these changes have
been sitting in linux-next for a while".
So, what's the relationship between linux-next and

Or they just write it manually?
Thanks.

Hi,
Suppose I have two kernels, one is A.B.C build by people Tom. And
the other is A.B.C build by Jerry. The source code have been deleted
after kernel is build and installed. Now I want to know whether the
source code of these two kernel is the same (even if they have the same
name). All I have

Hi,
I check kernel code and found that GFP_ATOMIC allocation will
use emergency pool and maybe failed if emergency pool is not
enough. And GFP_ATOMIC doesn't trigger reclaim (because of
ATOMIC) even if there are a lot of page caches. So my question
is how to avoid or reduce GFP_ATOMIC allocation
Hi,
The documentation of jprobe says that we must call jprobe_return()

could we use it to skip probed function?
Thanks.
