io_uring: don't rely on weak ->files references
Grab actual references to the files_struct. To avoid circular references
issues due to this, we add a per-task note that keeps track of what
io_uring contexts a task has used. When the tasks execs or exits its
assigned files, we cancel requests based on this tracking.
With that, we can grab proper references to the files table, and no
longer need to rely on stashing away ring_fd and ring_file to check
if the ring_fd may have been closed.

0e7dd826b4 ("kmap: Add stray access protection for device pages"): kernel BUG at arch/x86/mm/physaddr.c:80!
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/weiny2/linux-kernel.git lm-pks-pmem-for-5.10-v11
commit 0e7dd826b4695353fbdf1033b3bee6c1abd39a2b
Author: Ira Weiny <ira.weiny(a)intel.com>
AuthorDate: Tue Mar 31 13:50:26 2020 -0700
Commit: Ira Weiny <ira.weiny(a)intel.com>
CommitDate: Tue Oct 6 19:23:29 2020 -0700
kmap: Add stray access protection for device pages
Device managed pages may have additional protections. These protections
need to be removed prior to valid use by kernel users.
Check for special treatment of device managed pages in kmap and take
action if needed. We use kmap as an interface for generic kernel code
because under normal circumstances it would be a bug for general kernel
code to not use kmap prior to accessing kernel memory. Therefore, this
should allow any valid kernel users to seamlessly use these pages
without issues.
Because of the critical nature of kmap it must be pointed out that the
over head on regular DRAM is carefully implemented to be as fast as
possible. Furthermore the underlying MSR write required on device pages
when protected is better than a normal MSR write.
Specifically, WRMSR(MSR_IA32_PKRS) is not serializing but still
maintains ordering properties similar to WRPKRU. The current SDM
section on PKRS needs updating but should be the same as that of WRPKRU.
So to quote from the WRPKRU text:
WRPKRU will never execute speculatively. Memory accesses
affected by PKRU register will not execute (even speculatively)
until all prior executions of WRPKRU have completed execution
and updated the PKRU register.
Still this will make accessing pmem more expensive from the kernel but
the overhead is minimized and many pmem users access this memory through
user page mappings which are not affected at all.

8af7da1149 ("kmap: Add stray access protection for device pages"): kernel BUG at arch/x86/mm/physaddr.c:80!
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/weiny2/linux-kernel.git lm-pks-pmem-for-5.10-v10
commit 8af7da1149db0a4bd752fabcdb64d80482b7be24
Author: Ira Weiny <ira.weiny(a)intel.com>
AuthorDate: Tue Mar 31 13:50:26 2020 -0700

kmap: Add stray access protection for device pages
Device managed pages may have additional protections. These protections
need to be removed prior to valid use by kernel users.
Check for special treatment of device managed pages in kmap and take
action if needed. We use kmap as an interface for generic kernel code
because under normal circumstances it would be a bug for general kernel
code to not use kmap prior to accessing kernel memory. Therefore, this
should allow any valid kernel users to seamlessly use these pages
without issues.
Because of the critical nature of kmap it must be pointed out that the
over head on regular DRAM is carefully implemented to be as fast as
possible. Furthermore the underlying MSR write required on device pages
when protected is better than a normal MSR write.
Specifically, WRMSR(MSR_IA32_PKRS) is not serializing but still
maintains ordering properties similar to WRPKRU. The current SDM
section on PKRS needs updating but should be the same as that of WRPKRU.
So to quote from the WRPKRU text:
WRPKRU will never execute speculatively. Memory accesses
affected by PKRU register will not execute (even speculatively)
until all prior executions of WRPKRU have completed execution
and updated the PKRU register.
Still this will make accessing pmem more expensive from the kernel but
the overhead is minimized and many pmem users access this memory through
user page mappings which are not affected at all.

[mm] a4d63c3732: will-it-scale.per_process_ops -4.2% regression
by kernel test robot
Greeting,
FYI, we noticed a -4.2% regression of will-it-scale.per_process_ops due to commit:
commit: a4d63c3732f1a0c91abcf5b7f32b4ef7dcd82025 ("mm: do not rely on mm == current->mm in __get_user_pages_locked")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 104 threads Skylake with 192G memory
with following parameters:
nr_task: 100%
mode: process
test: mmap2
cpufreq_governor: performance
ucode: 0x2006906
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen(a)intel.com>
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml

[mm] 70e806e4e6: will-it-scale.per_process_ops 2.7% improvement
by kernel test robot
Greeting,
FYI, we noticed a 2.7% improvement of will-it-scale.per_process_ops due to commit:
commit: 70e806e4e645019102d0e09d4933654fb5fb58ce ("mm: Do early cow for pinned pages during fork() for ptes")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 104 threads Skylake with 192G memory
with following parameters:
nr_task: 100%
mode: process
test: mmap2
cpufreq_governor: performance
ucode: 0x2006906
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------+
| testcase: change | will-it-scale: will-it-scale.per_process_ops 2.0% improvement |
| test machine | 104 threads Skylake with 192G memory |
| test parameters | cpufreq_governor=performance |
| | mode=process |
| | nr_task=100% |
| | test=mmap1 |
| | ucode=0x2006906 |
+------------------+---------------------------------------------------------------+
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
