| |
This is a v2 of the https://lkml.org/lkml/2020/4/28/1626 series. Please have look at v1 to find out more about motivation and details. It is based on the latest dev.2020.05.17a Paul's branch.
Short changelog (v1 -> v2): - Combine some patches, thus reduce the overall number; - Switch one line comment type from "/* */" to "//"; - Improve commit messages of some patches; - For tiny-RCU we just do synchronize_rcu() followed by kvfree() for single-argument of kvfree_rcu(); - Drop the dynamic rcu_head attaching techniques + related patches; - Reduce duplication of code in some functions; - Added more comments for better understanding of code.
There is one patch related to "mm": "Rename kvfree_rcu() to local variant" please note, it does not change any functionality, only renaming is done.
Joel Fernandes (Google) (3): rcu/tree: Keep kfree_rcu() awake during lock contention rcu/tree: Skip entry into the page allocator for PREEMPT_RT rcu/tree: Make debug_objects logic independent of rcu_head
Sebastian Andrzej Siewior (1): rcu/tree: Use static initializer for krc.lock
Uladzislau Rezki (Sony) (12): rcu/tree: Repeat the monitor if any free channel is busy rcu/tree: Simplify KFREE_BULK_MAX_ENTR macro rcu/tree: Move kfree_rcu_cpu locking/unlocking to separate functions rcu/tree: cache specified number of objects rcu/tree: Maintain separate array for vmalloc ptrs rcu/tiny: support vmalloc in tiny-RCU rcu: Rename *_kfree_callback/*_kfree_rcu_offset/kfree_call_* mm/list_lru.c: Rename kvfree_rcu() to local variant rcu: Introduce 2 arg kvfree_rcu() interface rcu: Support reclaim for head-less object rcu: Introduce single argument kvfree_rcu() interface lib/test_vmalloc.c: Add test cases for kvfree_rcu()
