Merge tag 'rust-i2c-for-7.3' into i2c/i2cgrafted
i2c: rust: mark I2cAdapter methods as inline A single cleanup for the Rust I2C abstractions, targeting 7.3. `I2cAdapter::get`, `inc_ref`, and `dec_ref` are trivial wrappers around `i2c_get_adapter`/`i2c_put_adapter` and were showing up as their own symbols in the build. Mark them `#[inline]` so they get folded into their callers instead. Signed-off-by: Igor Korotin <igor.korotin@linux.dev> * tag 'rust-i2c-for-7.3': i2c: rust: mark I2cAdapter methods as inline

+ select KERNFS
+ select PROC_CPU_RESCTRL if PROC_FS
+ help
+ Some architectures provide hardware facilities to group tasks and
+ monitor and control their usage of memory system resources such as
+ caches and memory bandwidth. Examples of such facilities include
+ Intel's Resource Director Technology (Intel(R) RDT) and AMD's
+ Platform Quality of Service (AMD QoS).
+
+ If your system has the necessary support and you want to be able to
+ assign tasks to groups and manipulate the associated resource
+ monitors and controls from userspace, say Y here to get a mountable
+ 'resctrl' filesystem that lets you do just that.
+
+ If nothing mounts or prods the 'resctrl' filesystem, resource
+ controls and monitors are left in a quiescent, permissive state.
+
+ On architectures where this can be disabled independently, it is
+ safe to say N.
+
+ See <file:Documentation/filesystems/resctrl.rst> for more information.

+ Enabled by the architecture when the RMID values depend on the CLOSID.
+ This causes the CLOSID allocator to search for CLOSID with clean
+ RMID.
