Update lz4 module using official repository from revision [1]. Keep in mind lz4hc wasn't updated thus it is not used. It may not compile anymore. [1]: https://github.com/lz4/lz4/tree/4ebe313e00aa52c837ee029ede39a0503a8a39c9

[ Upstream commit a88e03cf3d190cf46bc4063a9b7efe87590de5f4 ] snprintf() returns the number of bytes it would have printed if there were space. But it does not count the NUL terminator. So that means that if "count == copied" then this has already overflowed by one character. This bug likely isn't super harmful in real life.

When the ->init_lock is released in zram_reset_device(), disksize_store() can come in and try to allocate meta, but zram_reset_device() is freeing free meta, so cause races.

Some DT devices, mainly smartphones, do need more trip points to allow more fine grained thermal mitigations, hence allowing a better user experience (and overall performance), for example, by lowering the CPU clocks just a little for each temperature step.

I get this error when I compile with IPC_LOGGING disabled. I have no clue how to fix seeing as https://github.com/RealJohnGalt/GaltsGulch-sm8150 has exact same cma.c as I do and that kernel can be compiled as far as I can tell without IPC_LOGGING. So just include where it is declared? Anyone please advise if you know where it went wrong ../mm/cma.c:497:9: error: implicit declaration of function 'fatal_signal_pending' [-Werror,-Wimplicit-function-declaration] if (fatal_signal_pending(current)) ^ 1 error generated.

Copying from user to a global variable inside the driver is unsafe and insecure: allocate and free the memory used for copying from userspace in the functions doing it. This also has the good side effect of solving a build failure when the kernel is built with GCC >=4.9 Change-Id: I04bfb0cd0ffb6870481f639818cf8c51191d927d
The smallest string that this function deals with is "1", which is of size 1. Correct the if to allow this case. Change-Id: Iaa68bcc452a3428d4752e5c34c98d0bd2e926c5a Signed-off-by: MarijnS95 <marijns95@gmail.com>

For portrait mode with dual camera synchronization, enable initial skip to make sure two sensors both start streaming with synchronization signal. This fixed the portrait mode switching stability issue.

…policy free
detect_share_cap_flag() calls cpufreq_cpu_get() to get cpufreq
policy for each possible cpu, meanwhile, it also increments the
kobject reference count of policy to mark it busy. However, a
corresponding call to cpufreq_cpu_put() is ignored to decrement
the kobject reference count back, which may lead to a potential
stuck risk that percpu cpuhp thread deadly waits for dropping
of kobject refcount when percpu cpufreq policy free.
The call trace of stuck risk could be:
cpufreq_online() //If cpufreq initialization failed, goto out_free_policy.
->cpufreq_policy_free() //Do cpufreq_policy free.
->cpufreq_policy_put_kobj()
->kobject_put() //Skip if policy kfref count is not 1.
->cpufreq_sysfs_release()
->complete() //Complete policy->kobj_unregister.
->wait_for_completion() //Wait for policy->kobj_unregister.
With this patch, the cpuhp thread can be easily exercised by
attempting to force an unbind of the CPUfreq driver.

lybxlpsv said that some unity games also looking for the cpu_capacity to determine about their decision on affinity setup.
