Thanks for doing this series as a PoC, counter to the module_firmware_crash()

This applies to today's linux.git (note the base-commit tag at the

When wlcore_fw_status() returns an error code, a pairing
runtime PM usage counter decrement is needed to keep the
counter balanced. It's the same for all error paths after
wlcore_fw_status().

Hi Bjorn,
In fact, most usage of pm_runtime_get_sync() is correct. I made
a static analysis tool to check this imbalance in kernel and
found about 80 bugs in dirvers. Some of my patches have been
accepted and I'm trying to patch the rest as soon as possible.

Dinghao

Dealing with the return value of get_user_pages*() variants has a few
classic pitfalls, and this driver found one of them: the return value
might be zero, positive, or -errno. And if positive, it might be fewer
pages than were requested. And if fewer pages than requested, then
the caller should ret
Hi,
Note that I have only compile-tested this series, although that does
also include cross-compiling for a few other arches. I'm hoping that
this posting will lead to some run-time testing.
Also: the proposed fix does not have a "Fixes:" tag, nor does it
Cc stable. That's because the issue has b
This code was using get_user_pages*(), in a "Case 2" scenario
(DMA/RDMA), using the categorization from [1]. That means that it's
time to convert the get_user_pages*() + put_page() calls to
pin_user_pages*() + unpin_user_pages() calls.
There is some helpful background in [2]: basically, this is a
When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
