Commit Id ---> 5037be168f
The reason I was asking for the commit ID is because I saw that
clone_endio()
occurs in the oops which means that the dm driver is involved. An
important fix
for the dm driver went upstream recently, namely d37753540568 ("dm: Use
kzalloc
for all structs with embedded biosets/mempools"). Can you double check
whether
that commit it present in your tree? If it is not present, please
update to the
latest master and retest. If it is present, please report how to
reproduce
this oops to Kent Overstreet, Jens Axboe, linux-block and Mike Snitzer.
Thanks,
Bart.
Yes, the fix is present in the tree, which I have tested.
Steps to reproduce:
Step1: Clone and Install avocado git clone
https://github.com/avocado-framework/avocado.git
Step2: Clone
https://github.com/avocado-framework-tests/avocado-misc-tests.git
Test case is
https://github.com/avocado-framework-tests/avocado-misc-tests/blob/master/memory/memhotplug.py
Step3: Command to run the test is avocado run
avocado-misc-tests/memory/memhotplug.py

Venkat.
