Git tree request
by Jessica Yu
Hi 0-day team,
I'd like to swap out the repo I currently have listed (github) to
the following new repo at git.kernel.org:
git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux.git
Could you add the above repo to the 0-day testing list? I'd also like
to have the modules-next and modules-linus branches regularly tested,
and would also like to request build success notifications from the
kbuild bot.
Thank you!

[mm] ee85715d28: BUG: sleeping function called from invalid context at mm/swap.c:741
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/next
commit ee85715d2898ab6cf61e30db4d2df8f7e58bd82d
Author: Paul E. McKenney <paulmck(a)linux.vnet.ibm.com>
AuthorDate: Fri Nov 25 12:48:10 2016 -0800

mm: Prevent release_pages() RCU CPU stall warnings
This commit adds a cond_resched_rcu_qs() calls in release_pages() in
order to prevent RCU CPU stall warnings. More importantly, this change
allows RCU grace periods to complete despite "longer than average"
loops in release_pages().
Note that this is a case of "treating the symptoms". In addition, it
is quite possible that the cond_resched_rcu_qs() needs to be in some
lower-level function that might have been inlined into release_pages().
In short, this one is experimental in nature.

mm: ovl: copy-up on MAP_SHARED
A corner case of a corner case is when
- file opened for O_RDONLY
- which is then memory mapped SHARED
- file opened for O_WRONLY
- contents modified
- contents read back though the shared mapping
Unfortunately it looks very difficult to do anything about the established
shared map after the file is copied up. Instead when a read-only file is
mapped shared overlayfs copies up the file before actually doing the map.
This may result in unnecessary copy-ups (but so may copy-up on open(O_RDWR)
for exampe).
We can revisit this later if it turns out to be a performance problem in
real life.
