[PATCH v2] nbd: replace kill_bdev() with __invalidate_device() again

by SunKe

From: Munehisa Kamata <kamatam(a)amazon.com> Commit abbbdf12497d ("replace kill_bdev() with __invalidate_device()") once did this, but 29eaadc03649 ("nbd: stop using the bdev everywhere") resurrected kill_bdev() and it has been there since then. So buffer_head mappings still get killed on a server disconnection, and we can still hit the BUG_ON on a filesystem on the top of the nbd device. EXT4-fs (nbd0): mounted filesystem with ordered data mode.

[PATCH] cpufreq: schedutil: Don't skip freq update when limits change

by Viresh Kumar

To avoid reducing the frequency of a CPU prematurely, we skip reducing the frequency if the CPU had been busy recently. This should not be done when the limits of the policy are changed, for example due to thermal throttling. We should always get the frequency within the new limits as soon as possible. Fixes: ecd288429126 ("cpufreq: schedutil: Don't set next_freq to UINT_MAX") Cc: v4.18+ <stable(a)vger.kernel.org> # v4.18+ Reported-by: Doug Smythies <doug.smythies(a)gmail.com> Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- @Doug: Can you please provide your Tested-by for this commit, as it already fixed the issue around acpi-cpufreq driver.

[PATCH] mm/usercopy: Use memory range to be accessed for wraparound check

by Isaac J. Manjarres

Currently, when checking to see if accessing n bytes starting at address "ptr" will cause a wraparound in the memory addresses, the check in check_bogus_address() adds an extra byte, which is incorrect, as the range of addresses that will be accessed is [ptr, ptr + (n - 1)]. This can lead to incorrectly detecting a wraparound in the memory address, when trying to read 4 KB from memory that is mapped to the the last possible page in the virtual address space, when in fact, accessing that range of memory would not cause a wraparound to occur. Use the memory range that will actually be accessed when considering if accessing a certain amount of bytes will cause the memory address to wrap around.
